is that good or bad? from the world's leading reporters and analysts, here is what's happening from around the world. this is "worldfocus." made possible, in part, by the following funders -- good evening. i'm martin savidge. we're going to begin tonight with iraq, where for months, the iraqi government and the u.s. have been sending the message that the security situation has steadily improved. american troops, 132,000 of them, are now in a support role. and in recent days the government has relaxed security in baghdad. but once again today, there was violence. a wave of it killing at least 48 people and wounding more than 250. the attacks were in a town near mosul in the north and in baghdad itself. the continuing violence and why it is happening is our "lead focus" tonight. we start with hoda abdel hamid of al jazeera english.

>> reporter: early morning in iraq and dozens of people are already confirmed dead in various attacks. each underscoring one of the many conflicts that still plague the country. in baghdad, officials say five bombs went off. the deadliest ones targeted day laborers waiting for a job. one of the bombings in hay al amel in the west of the capital, one of the few areas where sunnis and shias still live side by side. the bomb was hidden inside a cement bag, says this man. moments later, a second blast, further north in western baghdad, also killed day workers, this time in a predominantly shia neighborhood. attacking workers is a bid to stop the already slow reconstruction efforts which the americans are focusing on to bring stability, pouring million of dollars in projects. these attacks came less than 24 hours after workers under

government orders started removing protective blast walls around the capital. the walls were central to the u.s. strategy during the military surge. but the deadliest attacks were in khanzaa, a so-called disputed territory 20 miles north of mosul in the southern edge of the kurdish region. tensions in the area have risen considerably with both the government in baghdad and the kurdish one in erbil contending the land and its oil wealth as theirs. khanzaa is now under control of the kurdish soldiers, the peshmerga. monday's blast targeted the shabak community, a religious minority which fled mosul as the city fell into the grip of violence. mosul is now considered the most dangerous city in iraq, and the u.s. pullback out of towns and cities seems to have left the door open for an increase in attacks here and around the country. a reality both baghdad and washington are well aware of. lately prime minister al maliki,

during a visit to washington, has already warned that troops could stay in iraq after 2011. the deadline for the final withdrawal. abdel hamid, al jazeera. for more about this latest outbreak of violence in iraq, we are joined tonight by douglas ollivant. mr. ollivant served two tours in iraq as a lieutenant colonel in the army. and until two months ago was director for iraq policy at the is national security council in both the bush and the obama administrations. welcome. >> thank you. >> we saw dozens of people killed in iraq on friday and dozens more unfortunately today. should we be concerned that the security suation there is deteriorating now that the u.s. troops have pulled back and get ready to pull out? >> martin, these are tragic events especially if the people who are killed and their families but bottom line to your question is, no. these events are isolated acts of terrorism. admittedly repeated isolated acts of terrorism but they're not having any strategic effect. >> who do we think is behind

this? >> almost certainly al qaeda and iraq. >> and their purpose? >> their purpose is to, first, try to reignite the civil war between the sunnis and the shia in iraq, and also to demonstrate their relevance,ta they're still a player in iraq. >> and why would they want to retrigger a civil war, as you call it? >> well, al qaeda, which a radical sunni muslim organization, doesn't like the shia. they think that they are muslim apostates. even worse know that the christians. and they would love for the iraqi sunnis to rise up against them, overthrow the shia government, and reestablish a sunni caliphate in iraq. that's not going to happen but that's their aim. >> there was superior, not that long ago that you would have a bombing say that the shias or the sunnis and then the shias would respond against the sunnis. why aren't we seeing this tit for tat? >> i think chargely the tit for tat accelerated in a civil war.

we saw a civil war between the sunni and the shia muslims in iraq but that war is over. the shia have won. there's a shia government fully established. the sunnis have accepted that. they've reconciled with it, largely. the awakening movements of which we've heard so much have become aligned with the central government and there's no longer really anything for them to fight over. >> do you think this will slow down in any way the u.s. plans to get out of iraq and the timetable? >> not at all. so long as we know to see that the government is in control and that there's not a malicious-style warfare sectarian war going on underneath that there is no retaliation for these bombings there is no job to slow down the u.s. withdraw. >> you seem to imply sort of a baseline of violence for some time within iraq. >> ttely right. i mean iraq is going to continue to be a violent place. the violence coming from these al qaeda attacks. they are going to continue to try to demonstrate that they are

relevant in iraq. but that doesn't mean that there's going to be a return of the violence that we saw again in the bad days of 2006 and '07. >> okay just about out of time. but do you think that the united states has moved on now, say, more focused on afghanistan than in iraq? and is it too early for that? >> militarily it's clearly time to shift to afghanistan. iraq is now our test case for soft power. they need diplomacy. they need economic development. they need communications, but, no, the military effort is going to shift to afghanistan. >> douglas ollivant, thank you very much for joining us. >> thank you very much, martin. with american casualties rising sharply in afghanistan, the top american commander there says the taliban have gained the upper hand in the war. in an interview with "the wall street journal," general stanley mcchrystal said american casualties will regain high for months to come. general mcchrystal said the taliban are moving beyond their traditional strongholds in southern afghanistan to threaten formerly stabile areas in the north and west.

"it's a very aggressive enemy right now," general mcchrystal said in the interview saturday at his office in a fortified nato compound in kabul. "we've got to stop their momentum." it's hard work." mcchrystal said the u.s. is shifting its strategy by putting more troops in heavily populated areas to protect the civilians. there are now 62,000 americans in afghanistan. >> this country is still sending more troops to afghanistan and so is australia, which has just over 1,000 soldiers there, but sending in more to help provide security during the presidential election ten days from now. sally sara of australia's abc is embedded with some of them in the middle east, as they prepare for their deployment to afghanistan. >> reporter: they start training at dawn before the middle east and desert heats up to 45 degrees. these australian troops are only two days away from afghanistan. after many months of preparation, they are ready to take on the taliban.

>> what we don't do is give these bastards an edge. if they want to kill us, then they are going to fight for it all the way. because they would like nothing more for every one of us to dead, that would make their day. >> reporter: for many of these soldiers, this is their last chance to practice these drills before they touch down in afghanistan. warrant officer alex mol watches over the soldiers with a mixture of pride and anxiety. his own son is already serving on the front line in afghanistan. >> i have a son who is out on the ground fighting at the moment, so when we have an incident, that always hits home. the sons of many other families are on their way too. private patrick gilmore from adelaide will be going into combat for the firstime.

he's been in the army for less than two years. he's nervous about what's ahead, but confident his training will get him through. >> there will always be risks but that's what you signed up for. i try not to think about it too much. i'm not really too worried. >> reporter: the troops receive a final first aid lesson before they fly out. the number one danger for these soldiers will be improvised explosive devices, or ieds. the blasts have already claimed australian casualties. the troops are going in to afghanistan at an extremely dangerous and sensitive time. it's not only ten days to go until the presidential election and now more than ever before there's a vital link between security and democracy. many of these young soldiers will be putting their lives on the line as coalition forces step up the fight against the taliban. sally sara, abc news. in iran today, president mahmoud ahmadinejad fired four senior intelligence ministry officials, part of a purge targeting officials who disagreed with that crackdown on protesters after the disputed presidential election in june.

over the weekend, a top prosecutor acknowledged that some of those arrested had been tortured while in prison. he called such treatment "painful accidents" that cannot be defended, and said those involved should be punished. in asia, typhoon morakot has been downgraded to a tropical storm, but not before it caused widespread destruction in several countries. the typhoon dumped as much as 80 inches of rain in parts of taiwan, where 400 or more people were reported buried and are unaccounted for after a mudslide in one village yesterday morning. in china, hundreds of villages and towns were flooded and more than 2,000 houses collapsed. almost a million people were evacuated. and in the philippines, the storm killed at least 22 people over the weekend. today, another typhoon,

etau, slammed into the west coast of japan causing floods and landslides that killed at least 13 people. the typhoon is expected to hit just east of heavily populated tokyo tomorrow afternoon. tokyo was also jolted yesterday by a powerful earthquake that rocked buildings and rattled furniture in the capital city but caused no major damage. the quake measured 7.1 but was centered well off shore, deep under the pacific ocean. japan's highly vulnerable to earthquakes and is struck by about 20% of the world's quakes. experts put the chances of an earthquake centered near tokyo at 70% in the next couple of decades and warn that thousands could die. mark willacy of abc in australian, looks at how people are trying tprepare. >> reporter: this is how you shake, rattle and roll tokyo style. inside this stimulator, people are given a taste of what it's

like to experience a magnitude 7 earthquake. >> reporter: 14 years ago at kobe, more than 6,000 people lost their lives. but it's feared that with a population of more than 20 million, greater tokyo could suffer even more carnage. experts say the probability of a 7 quake striking tokyo in the next generations is 70%. and it's estimated that it could cause more than a trillion dollars worth of damage. easily making it the most expensive calamity in world history. >> translator: in the worst case 10,000 will die and more than 100,000 will need hospital treatment. >> reporter: in 1923 the great kanto earthquake measuring a mammoth 8.3 on the rishter scale truck tokyo and yokohama.

140,000 people perished. every year on the anniversary, tokyo is put through its paces but last night the city got a taste of the real thing with a magnitude 7 quake shaking buildings and stopping trains. luckily the tremor's epicenter was 300 kilometers off the coast. it's feared that the next big one could be a lot closer to home. mark willacy, abc news, tokyo. some health news tonight. while the united states and other countries prepare for a possible large new outbreak of the h1n1 flu this fall, british researchers said today that children 12 years old and under should not take antiviral drugs like tamiflu. that's because the side effects may outweigh the benefits. those side effects include nausea and vomiting, while drugs

splay shortened the duration of the flu by only a day or so. >> that prospect of a broad new outbreak of the h1n1 flu was one issue on president obama's mind as he completed a summit meeting in mexico today with president felipe calderon and with prime minister stephen harbor. >> our three governments have worked closely, collaboratively and responsibly with science as our guide we resolve to continue to take all necessary preparations and precautions to prepare for the upcoming flu season and protect the health of our people. >> the president also addressed continuing attempts to crackdown on mexico's violent drug cartels and defended the mexican government's efforts in that battle. >> as i've said on many occasions, i heartily commend president calderon and his government for their determination and courage in taking on these cartels. and the president reaffirmed his governments committed to transparency, accountability and human rights as they wage this difficult but necessary fight. for more on the president's trip to mexico, we're joined

here once again by sharon o'neil, a fellow in latin american studies at council on foreign relations here in new york. welcome back. >> thank you. >> so this is president obama's second trip to mexico. what is the significance of this particular meeting? >> well, this is a meeting that's been held annually for the last four years. it's a north america summit bringing together prime minister harper of canada, president obama offed the united states and calderon of mexico. so part of this larger format. >> i was looking at flu season just around the corner and i understand talking about wife is on the, the agenda here and it's said that there will be greater cooperation p i'm just wondering, what exactly is does that mean. >> unprecedented cooperation when swine flu broke now the april. we saw scientists from canada, the united states, get together, scientists from mexico too to actually figure out what swine flu was and then to try to control it. so we'll see that continue and we may also see the movement of vaccines of other types of treatments in the fall season when sbf, when everyone thinks it will return. >> so we see good cooperation on

swine flu. trade, though has been a contentious issue and i'm wondering what are the problems there and how are we doing in solving them? >> you then is a contentious issue. we obviously have very close ties with both of our neighbors. they're both the first and the large largest trading partner for the united states. they both worry about bio american clauseses in the stimulus packages and that that would continue and deepen and particularly on the mexican side there's a dispute over trucks and mexican trucks coming into the united states. under nafta, it was promised the u.s. would allow these trucks in but they still haven't and it's been over 15 years. >> any progress made. >> you know they're working on it and what the obama administration says that they're in discussions. trying to come up with some sort of agreement. worries on the united states' side about safety but also fulfills our navigations under nast but still don't have the reslution. >> and drug violence. just yesterday a gun lawyer was gowned down in monterrey.

>> $1.4 billion over three years. and we also see a lot of day-to-day communication between u.s. forces and bureaucracies and the mexican bureaucracies but this will really be a long-term solution or a long-term issue for the two countries to resolve. >> if i were to ask you, well, what's the biggest challenge that still exists say between the u.s. and mexico? is it something we've discussed or more to it? >> you know the biggest challenge is the fact that we're so interconnected as countriesta all of these issues are on the table and you can't just look at one in isolation. you can't just look at the economy, just look at health, just look at issues like climate change or just at security. they're all intertwined so solutions to each one are going to involve other one and so thinking about it in its holistic way is really the biggest challenge. >> shannon o'neil, as always, thank you very much. >> my pleasure.

secretary of state hillary clinton continued her 11-day visit to africa today. in the democratic republic of congo, clinton drew attention to the widespread problem of sexual violence in that country where the army and rebel groups continue to attack villages and kill and assault civilians. clinton has also been in angola, where she praised steps that country has taken toward democracy. she refused to comment on what is seen as a growing rivalry for influence in that oil-rich country between the united states and china. and in tonight's signature story, we want to take another look at the increasingly important trade relationship between china and africa. china recently surpassed the united states as africa's biggest trading partner to the tune of $107 billion last year. that's a remarkable tenfold increase just this decade. some of this trade does involve countries such as angola, sudan, zimbabwe, which have been implicated in human rights abuses.

but as "worldfocus" special correspondent martin seemungel first reported last year from kenya and tanzania, china's influence is much broader. >> reporter: these young kenyans already speak english. a legacy of the british emfire africa but now they have decided to learn -- chinese. this is the confucius institute at nairobi university. for these students taking chinese is, as they say, a no-brainer. >> this language is important. because of their -- because china is growing so much. and the influence of china in africa and most of the world is higher than it was last year. >> reporter: africa's one of benefit of chin's economic boom. the chinese are bullish on africa. they want the raw materials to fuel their ravenous economy.

one-third of what's exported from africa to china is oil. but more and more goods are moving in the other direction. from china to africa. arriving, as it were, right on the continent's doorstep. all the goods that come from china to east africa arrive here at the port of mombasa. in fact, the massive cranes unloading the containerships are also made in china. it is just the first clue of the china connection. the mombasa to nairobi road, the vital link from the east coast to the interior of africa. it used to be the worst 350-mile stretch of road in the region. eight years ago a section was rebuilt by the chinese. ahmed abdullah has just begun his 1,200-mile journey from mombasa on the eastern edge of africa to congo.

so what source of things impoirted from china are those trucks carrying? just about everything you imagine from pots and pan to the most sophisticated computer, all cheap. go to the electronic shops and you'll find them. shoes from china seem to be everywhere. >> you can see they are from china. >> reporter: from chin? >> yeah. >> reporter: the cheapest ones? >> yeah. >> reporter: there are loads and loads of them, overwhelming african shoemakers like this man. his name is emmanuel and he lives in da sa lam tanzania where we travel next. one employee makesshoes, also belts and handbags. heesz it's difficult for us to compete chinese products. they are sold at much lower

prices than what we sell. they are cheap. $6 for a pair of the chinese shoes. about $4 less than the tansanian shoes. in a country where people don't have much money, no contest. u.s. diplomat george aldridge monitors chinese commerce in east africa. >> this might be the great irony of our new century so far. that an ostensibly communist country has become the most ruthless capitalist count row in the world. undercutting producers, not just american producers, but african producers. >> reporter: this is a fairly typical market by african standards. and many of the products here, a growing number of the products here, are chinese. but it's not just the products that are from china. many of the people who own these shops are from china. the man if the shop next door blames the chinese for undercutting everyone. if we could chase them away, he

says, we would. it would be better if they weren't here. the big surprise in all this is that china doesn't see itself as a competitor or the so-called ruthless capitalist aggressor. >> and since we are both belonging to the -- country and we have similar experience and similar tasks for chinese and african commons to lift their economy. >> reporter: if you drive around the capital of tanzania, it doesn't take long to find the chinese at work. we were allowed onto one building site and it helps understand how chinese companies are consistently able to win contracts over western companies. eight chinese construction workers. 50 tansanians. so far as the chinese go, they get no vacations to china, no holidays the entire time they're on this project and it lasts 24 years.

th --lasts two years. they only have one more year to go. meals they cook themselves. they work long hours but there is a noticeably relaxed interaction between the chinese and the tansanians. some of the chinese have worked in tanzania before and a bit like the young kernians learning mandolin they are learning swahili. not necessarily to make friends. it's clear they're here to do business, just like the chinese sending the cheap shoes, building roads and buying the oil. i'm martin sea mungel reporting for "worldfocus" in east africa. coming up later this month on the pbs series "wide angle," another story about how china has staked its claim in africa. in fact, the discovery of a vast underwater oil reserve in the west african nation of equatorial guinea caught the attention of not only the u.s. and china, but also some

soldiers of fortune bent on taking over the country and making its oil riches their own. it's called "once upon a coup." check your local listings for the program on pbs later this month and you can also find it online at pbs.org/wideangle. that's "worldfocus" here in monday evening. i'm martin savidge in new york. as always, we thank you for joining us and we hope to see you back here tomorrow and anytime on the web. until then, have a good night.
