so you're going to keep fighting, no matter what. "of course, for the sake of my granddaughter." he said. "we must protect ourselves to prove that ukraine exists." a fight for ukraine everyone here we met believes in. what keeps you hopeful? >> we understand that if we are together, we can fight with everything. and when our friends help us, we are better. >> reporter: the many ukrainians we've been speaking to from injured soldiers to politicians, they tell us they believe the u.s. and ukraine are still friends, and that the connection between these two nations runs far deeper than any disagreement between two presidents. and of course following president zelenskyy's visit to london this weekend, the quite literal warm embrace he received from european leaders as well as promises of aid and security guarantees, well, that had many here feeling that ukraine is not alone.

[ speaking valerian ] >> reporter: it seems like you

guys are really academically rigorous about these languages being real and plausible. why is that so important to you? >> unlike other props, you'll never interact with the real thing. and so if a sword looks like it's steel on screen, that's fine. it doesn't matter if it's actually plastic. it doesn't matter if it's actually sharp. a language doesn't exist beyond speaking it. that is the actual prop. you can't reach into the screen and grab a fake sword, but you can get the language. so it must be real. >> that was david pogue.

this is "cbs news roundup." i'm jessi mitchell in new york. president trump touted his new tariffs on canada, mexico, and china during his address to the nation. all three countries have announced their own tariffs on u.s. goods. but one country, china, may have already come up with a way around the trump tariffs. instead of exporting goods, china is exporting its factories. anna coren reports. >> reporter: a two-hour drive outside the cambodian capital phnom penh, a convoy of semi trailers passed by. moments later, an enormous arch greeted us with signage in two languages, the local language khmer, and beneath chinese. but it's very clear who is in charge of this special economic zone rising from the dirt. >> hello, sir. >> hello. >> reporter: the manager of this furniture factory invited us in. >> okay, okay, thank you. >> reporter: they moved here from china a month ago to produce otto man's to export to

the united states. most of the companies coming here are chinese? >> yes. >> reporter: and they're driving incentive to avoid u.s. tariffs. the u.s.-china trade war is the main reason for this explosion of chinese investment in cambodia. in 2016, before president trump took office, cambodian exports to the u.s. were roughly $3 billion. last year, they topped $12 billion, representing nearly 30% of the country's gdp. the cambodian government says more than half of the factories in cambodia are chinese-owned. >> to america? >> yeah. >> reporter: while chinese companies are skirting u.s. tariffs, an economist we spoke to say they are playing by the rules. but there are fears cambodia's economy could become collateral damage. are you concerned that president trump might put tariffs on cambodia, considering the chinese investments? >> yes. >> reporter: johnny's garment factory owner, mr. huang, moved

to cambodia 20 years ago, capitalizing on tax breaks and lower wages while still running factories in china. but when the trade war began in 2018, he moved all operations to cambodia and now exports 60% of his garments to the u.s. and who are your customers? >> walmart, costco. >> reporter: and he says those orders have only multiplied since president trump announced new tariffs. china's economy has been struggling. the property crisis and high youth unemployment. so the national people's congress is about laying the groundwork, the road map, if you like, to strengthen the economy for the year ahead. you know, this escalating trade war just adds to the level of uncertainty. but i spoke to an adviser to the chinese government last night, and he told me that despite all this noise, that behind the scenes, they are still hopeful scenes, they are still hopeful of a deal, a i was excited when i first heard of pronamel clinical enamel strength. this is a product that has our best enamel science yet.

commercial printing shop, reem printing, in york, pennsylvania. 61% of the county voted for president trump. how would you describe this area? >> we used to be a mecca for manufacturing. york was a real true leader. when i think, you know, when you heard the president talk on the trail, it hit home for us here. we lost a lot of jobs to foreign competitors. >> reporter: weigel voted for trump in november, and says since the election, he has been feeling more optimistic. how do you think he is doing so far on the economy? >> i mean, there is always room for improvement, of course. and right now it's a transition period. i think if we're honest with ourselves, regardless of whatever administration comes in every four to eight years, there is always a little bit of growth that has to occur. but i'm very happy. >> reporter: it's a feeling shared by william quinn, who owns the linden diner in york. how are you feeling about the economy right now? >> the economy is obviously not where it needs to be. but hopefully we're in the right direction now. >> reporter: a few weeks ago, quinn had to start charging more for egg dishes to accommodate the price surge and the

shortage. >> the price of everything, really. everything is fluctuating so much. there are certain items that you've got to protect. >> reporter: eggs at a diner, it's pretty much a staple. >> that's what it is, what we make our living off, eggs at a diner, all along. >> reporter: quinn also voted for trump and says the president needs time to help turn the economy around. >> every president needs time. we have to hope and invest and hope it drives our country forward and prices back to normal. >> reporter: when he was campaigning, he said on day one, i'll bring prices down. is that what you think he is doing? >> it doesn't happen overnight. >> reporter: that optimism you heard there is not really shared around the country. our new polling shows just 24% of americans say that they're feeling good about the economy compared to, say it's getting better, compared to 49% who said it's getting worse. and the top concern is inflation. that's among both democrats and republicans. the president likes to say

tariff is his favorite word in the dictionary. i can say that is not the sentiment shared among most republicans up here on capitol hill, particularly those from manufacturing states and big agriculture states concerned about rising prices, concerned about their industry exports. we even heard from senate majority leader john thune, who of course is from south dakota, expressing some concern, but also saying that he wanted to give the president latitude when it comes to tariffs and negotiations. >> caitlin huey-burns reporting. >> caitlin huey-burns reporting.

the largest and most ambitious art exhibit ever dedicated to the sport of boxing is on display at the norton museum in west palm beach, florida. it's called strike fast, dance lightly. and it's more than just a great bunch of paintings. rita braver paid a visit. >> i'm revealing all of you. i give you one more chance. who is the greatest? all right. >> a rugged sparring partner tosses some heavy leather at the champ, forcing him to give ground. >> reporter: muhammed ali is considered one of the greatest boxers of all time. but he also packed a punch with artworks like this 1967 drawing called "the crowd" seen from his perspective looking out from the ring. and some are smiling and some are frowning, right? >> i love that part, where he is

acknowledging not only did he have fans but he might have had some haters as well. >> reporter: four of ali's works are prominently featured in the whole exhibition devoted to boxing. winners, losers, and everything in between. >> it's -- it's big. it's bold. >> reporter: an curator arden sherman says the show here at the norton museum of art in west palm beach explores a host of different aspects about this most accessible of sports. >> it's rare to encounter a human of a certain age on this planet that doesn't have an understanding of the sport of boxing. >> reporter: others do seem to gravitate towards boxing. there are more than 100 works on display here. there are paintings, photographs, and sculptures, including many by and about women. this work by zoe buckman

features fabrics on boxing gloves. >> and she is someone who is consistently standing up for female rights and female empowerment. >> reporter: sherman says the exhibit comes as a very auspicious time. >> i mean, i believe as humans we find ourselves fighting for something or defending another thing. it is a contentious moment we live in. and what better way to express that but through the symbolism granted to us through the sport of boxing. >> reporter: so the give and take in works like these by george bellows, perhaps america's best known painter of boxing, seems to take on new meaning. this 1916 work called "introducing john l. sullivan" depicts not just the famous boxer and the announcer -- >> and these people, what are they up to? >> right.

they're the promoter, the moneymakers, the wheeler and dealers behind all of this. >> reporter: the exhibit features some heavyweight artists. there is roy lichtenstein's "sweet dreams" from 1965. and keith herring's late 1980s painted steel sculpture. what are the artists thinking, do you think? >> i think the artists are thinking about being alive. i think they're thinking about their own identity and how they navigate that in this world. i think they're thinking about love, violence, fantasy, death. >> one of the things about boxing and this act of being in a battle is it can be disorienting. >> reporter: among the most recent works is a pair of paintings from 2023 by jared mcgriff. >> the thing i think about with these two works is this idea of internal struggle and what it takes from an internal

determination and focus standpoint to reach this level of athleticism. >> reporter: and that could translate to anything, right? >> correct. >> reporter: of course, there are also flashes of humor. michael halsband's 1985 photos of artist andy warhol and jean michel basquiat in boxing gear, or the shot of a very young muhammed ali meeting the very young beatles in a miami gym on their first trip to the u.s. in 1964. he is boxing george's ear. >> absolutely. who would have thought that these five would be inside of this ring together and this would become this iconic image of box
