On that I fully agree with President Xi. But now the United States in the hottest nation on anywhere in the world.”The CCP leader suggestion US-China relations risk falling into the “Thucydides Trap”, where an established power is threatened by the rise of a rival, appeared to have somewhat bruised the ego of the President.In response, Mr Trump insisted relations between the two nations were on good terms, despite big differences on Iran, Taiwan and trade.The talks took place at Mr Xi’s residence, Zhongnanhai, this morning, with little sign of a significant breakthrough despite talks of “greater cooperation”.The US president conceded ‘tremendous damage’ had been done under Joe Biden’s administration | GETTYDuring talks, Xi Jinping also asked Mr Trump whether he would defend Taiwan in the event of war, to which the President confirmed he made no commitment.“He thinks they cannot have anything to do with what they are doing. He is very much against what they are doing,” Mr Trump told reporters on Air Force One during his return to Washington.He added: “I made no commitment either way. See what happens”.The President also said he would decide on arms sales to Taiwan in due course, with Mr Xi issuing a warning any mishandling of Taiwan could lead to “an extremely dangerous situation”.The Chinese leader suggested the pair could come into conflict unless the US changed its position of strategic ambiguity. Asked about the comments, Mr Trump replied: “I don’t think so. I think we will be fine.”Mr Trump had hoped to focus talks on trade and deals for China to buy more agricultural products and passenger planes, avoiding a repeat of the trade war ignited last year after the president’s tariff increases.The tumultuous relationship between the two nations was lauded by both leaders during the two-day visit, the first by a US President in almost a decade.The US agreed to allow 10 Chinese firms to purchase Nvidia’s second-most powerful chip, the H200, in a move that reflects a more collaborative sentiment between the two superpowers.Mr Trump also told Fox News the Chinese had agreed to purchase 200 Boeing jets from the American aeroplane manufacturer.Both leaders also discussed “ending the flow of fentanyl precursors” entering the US, as well as China buying American-produced agricultural products, the White House said.
