for the, the future ah, in the you with slowing in february on d, w. ah, [000:00:00;00] ah, this is d, w use live from berlin. the pentagon says it's detected a 2nd suspected chinese surveillance balloon over latin america. the 1st one floating above the u. s. heart land ignited a diplomatic storm that's kept the secretary of state visiting china. plus more

u. s. military aid for ukraine. the latest package, nearly doubles, keeps striking range against russian forces which continue attacking ukrainian stronghold and its sphere headed to fight against coven reachers. now, said researchers now say a new technology could become an effective weapon against caster. ah, nick spicer. welcome to the program. the pentagon says another suspected chinese spy balloon has been discovered this time flying over latin america. another balloon was seen floating above the u. s. heart land spotting his complicated washington in beijing's already strained relations and drawn americans attention to the sky. there is floating high above the united states on this balloon is causing major diplomatic problem spec on earth. thing is after this guy,

1st spotted over montana by curious residence. it's now believed to be a chinese espionage platform. last 35 minutes about china's decision to fly a surveillance balloon over the continental united states is both unacceptable and irresponsible. that's what this is about. as a violation of our sovereignty, it's a violation of international law. china rejects the spying claims and says it's a weather balloon that's veered off course. the white house isn't convinced, and a plan diplomatic trip to beijing has been abruptly called off. what this is done is created the conditions that undermine the purpose of the trip, including ongoing efforts to build a floor under the relationship and to address a broad range of issues that are of concern to the american people. i believe to the chinese people and certainly as well to people around the world. the trip was expected to be

a significant step in improving ties between the 2 countries. the balloon deflating those hopes. while some americans are demanding it be shot down is balloons are so huge that even that kind of that number of any additions that, that amount of any distance that towards it is only going to cause a very, very slow leak and was not going to come down immediately you can't just caught the balloon and it's going to go away. while the pentagon says the balloon poses no physical threat, it's no doubt doing damage to us china relations. relations the u. s. is determined to strengthen amid rising global tensions. and for more on this, i spoke earlier with the w east asia correspond william yang and asked him about what diplomatic repercussions the balloon incident might have on relations between the u. s. and china. so it's really showing how shaky the foundation of

the bilateral relationship is because a lot of the experts are saying if something as minor at this level, can just stop a highly anticipated trip that has taken both sides a month to prepare. then it really shows that there is basically no common ground for both sides to even start any kind of conversation. and so right now, what is going to constitute the conditions to restart? this message is basically beijing will have to show a more apologetic and lower it stands. and rather than sticking with what it is saying right now, which is that it claims that both either china or the u. s. has not even planned any kind of visit and the news of the visit is unity that are only being shared by the u. s. which is definitely a back walk back from the earlier statements that they've made about blink and visit. and beijing, of course, has been saying it's a whether not spy balloon. is that still the message or you're saying they're not

messaging and or at all domestically? they are sticking with the explanation and claim that it is still a scientific metro logical balloon that's basically veered off the original course by accident. but the us finding, contradict that because later on they find that the balloon actually changed course . and so this is basically showing that the chinese government official claiming is once again having a lot of holes for being like lighting on the outside world to be skeptical about. and they can't really stand on the ground and we are seeing how they toughen up their stands and become very defensive about it. and how is this william all being received among china's neighbors and in taiwan, where you are in particular so that the other neighbour neighboring countries are pretty quiet about it. the time ones for a ministry did issue a statement,

basically criticizing china's move of violating another countries sovereignty. and oh, so in shooting another country's air space and basically calling this an uncivilized move, that agent should stop immediately. ok, that was william yang for us from taipei. thanks so much. thank you. the united states has announced a new weapons package for ukraine. we're $2200000000.00. it includes new longer range missiles which could double the distance ukraine can strike and put russia supply lines in eastern ukraine within reach more armoured vehicles and air defense systems are also being provided. the latest package brings a total american support ukraine. since russia's invasion to more than $29000000000.00 to the aid comes as keys, forces are struggling against an intensifying russian assault on the city of back. moot, ukrainian president below to ms. lewinsky says his forces will hold back mood, quoting now, for as long as we can up until now,

the u. s. has declined to send ukraine longer range missiles for fear of provoking russia into escalating the conflict. so what changed as a question i put to military analyst frank lead, which well, nick, the message that you created asked for to call the tech homes. they're still not getting what they are getting are something called the ground, launched small diameter bombs, which about half the range of those for about 9 to 3 miles, a 150 kilometers or so. and you yourself hinted at purpose with the high mouse to which these missiles are designed already. the other launch systems down to 70 multiple loans, rocket systems. the russians have realized that clearly they've had their logistics wrecked by these over the last couple of months is mostly deals with, appreciate it so that move those logistical basis. further back behind the lines, the problem, the russians now is that these log a range missiles that the ukraine is getting 150 kilometers will now challenge.

those are not really important actually because what it will do is force to russians once again to push back their logistical chain way back behind their lines if they want them wrecked again, as happened in october, november, december. and just if we may get to back, move were intense fighting as it is continuing. president zalinski saying ukraine will fight for as long as we can. how long will that likely be to think okay, couple of things here as yet the russians have not got into the town of bath, not itself. it's a real dilemma for the ukrainians with for by pretty inform commentators and at least one west intelligence service that the american civil ready advised the ukrainians to, to withdraw from boston on their own terms in just in case they get surrounded and they can't withdraw on their own terms withdrawal and defies very difficult. it needs a lot of planning. so the, the calculation that you credit commanders have to make journals, albany, zalinski of course,

and some of the subordinate commanders is whether it's worth holding on as long as possible and measuring up against the huge cost at the moment clearly. so let's get the case. they'll be hanging on and do for the bigger picture. if i may know, i know you're not in jo biden's head, but is it fair to assume that washington calculated that? that losing back wooden desk is a bigger risk than escalating tensions with, with, with russia in terms of providing that extra new weaponry. yeah, i don't see escalation is a real risky. i don't think it's part of your calculations except and so far as the getting the sort of compromise rocket system run ask for much longer range attack of box itself is only important. strategically in the last of don't ask because of the resources that both sides are put into it. and it's a perfect example of military, some cost. in other words,

it's important says it derives after the losses that both sides i've taken so far and that they're willing to expend, to hold on to it. it has no other intrinsic strategic importance, say as it will give 7 support and give russia a small town. we should take 6 months to take a boat very ill for them for the much larger targets be on there. so you can kind of talk ok military analyst, franklin, which thanks so much for that insight. thank you. to turn out for a brief look at some other stories from around the world. russia and ukraine have exchanged dozens of prisoners of war. moscow say 63 russians were returned. well keith says 116 of their people were freed. bodies of 2 british volunteer aid workers killed in eastern ukraine in january were also returned to ukraine authorities, and sheila are struggling to contain deadly wildfires that are sweeping parts of the country so far. at least 13 people have died and over

a 140000 square kilometers of land have been devastated by the blazes caused by heat waves in the region. of frances has met with victims of the civil war in south today. thousands of people streamed towards the cathedral and juba t. m. c. the pontiff. earlier the pope made an impassioned plea for peace to warring factions in the country, saying that history would judge them harshly if they further delayed implementing a 2018 piece accord. the international community is marking world cancer day. cancer is among the leading causes of death worldwide. but now thanks to a cutting edge coven vaccine technology, we might be closer to stopping cancer. germany's by own tech is launching a trial in the united kingdom of personalized cancer vaccines. this autumn, more on the technology in this report. during the cove at 19 pandemic, vaccines were rolled out within a year faster than most experts believed possible. and messenger

r n a vaccines were among the 1st to gain approvals, they work by giving the body's immune system a preview of potentially dangerous invaders. a dose contains many copies of a short stretch of precise genetic information. the messenger r n a. it induces cells to start making proteins that are otherwise only found on a specific pathogen, like the proteins that stud the surface of sars covey to the virus that causes cove at 19. then wendy immune system encounters the virus, it quickly recognizes the invader and wipes it out, categorically messenger, any vaccines are proven to be exceptionally affected. they have proven to be able to protect people against severe and life threatening disease and consequently save millions of lives. there are different types of r, n a,

but all of them are coding molecules and that code can be rewritten. that's why many drug developers describe renee as medicinal software vaccines that use this software have a major advantage over other platforms. their codes can be easily altered to also make other proteins found on other disease causing microbes, teaching the immune system, how to fight them as well. and or in a can encode for proteins found not just an infectious diseases, but also for instance in cancers. in addition to messenger r n a, a range of other r, n a's play key roles and metabolism and health. so they also have potential as medicines . the cancer application is quite interesting because it is not a vaccine that will prevent cancer. but rather it is a therapeutic vaccine. it is a vaccine directed custom tailored to the caster of the,

of the patient. which in hanson's and directs the immune response to more efficiently clear the tumor around 20 or any treatments have been approved so far globally. and dozens more are in trials in a wide range of diseases. singapore has held his annual parade, celebrating the lunar new year. some $3000.00 performers danced and sang in the event with thousands more watching the display. this year was special because the parade was held live again after a 2 year pause due to pandemic, the event showcasing a pores, diverse culture with performers from the chinese community. joining ethnic malays, indians, and europeans. time for a quick recap now of our top story this, our the pentagon says it's detected his 2nd chinese spy balloon overt latin america a day after another such object was spotted over montana secretary of state antony
