US President Donald Trump delivered a stinging rebuke to China’s trade practices on Tuesday at the United Nations General Assembly, saying he would not accept a “bad deal” in US-China trade negotiations. Four days after deputy US and Chinese negotiators held inconclusive talks in Washington, Trump’s remarks were anything but conciliatory and emphasized the need to correct structural economic abuses at the heart of the countries’ nearly 15-month trade war. He said Beijing had failed to keep promises it made when China joined the World Trade Organization in 2001 and was engaging in predatory practices that had cost millions of jobs in the United States and other countries. “Not only has China declined to adopt promised reforms, it has embraced an economic model dependent on massive market barriers, heavy state subsidies, currency manipulation, product dumping, forced technology transfers and the theft of intellectual property and also trade secrets on a grand scale,” Trump said. “As far as America is concerned, those days are over.” Although Trump held out hope that the United States and China could still reach a trade deal, he made clear he wanted a deal that would rebalance the relationship between the two economic superpowers. “The American people are absolutely committed to restoring balance in our relationship with China. Hopefully, we can reach an agreement that will be beneficial for both countries,” Trump said. “As I have made very clear, I will not accept a bad deal.” Trump also recently said he was not interested in a “partial deal” to ease tensions with China, saying that he would hold out for a “complete deal.” Harsh rhetoric, stock fall US stocks gave up modest gains and fell into negative territory after Trump’s UN address, which some investors said marked a reversal of the more constructive tone that had surrounded the negotiations last week. “Trump’s comments to the UN were very antagonistic toward China. In the last couple of weeks there’s been optimism trade would go in a positive direction,” said Chris Zaccarelli, chief investment officer at Independent Adviser Alliance, an investment advisory group based in Charlotte, North Carolina. “It was the tone and the fact he listed out in great detail all the gripes the US has with China,” Zaccarelli said. “All that trade optimism that’s been building has been sucked out of the air and replaced with pessimism.” Trump’s speech highlighted the plight of US memory chip maker Micron Technology, which has become a symbol of US assertions that China fails to protect American intellectual property and steals it or forces the transfer of it. Two years ago Micron accused a Chinese state firm of stealing its chip designs. “Soon, the Chinese company obtains patents for nearly an identical product, and Micron was banned from selling its own goods in China,” Trump said, “But we are seeking justice.” He added that the United States lost 60,000 factories and 4.2 million manufacturing jobs since China joined the World Trade Organization. “The rhetoric around China and President Trump’s speech was as harsh as we have heard,” said Art Hogan, chief market strategist at brokerage National Securities Corp. in New York. China’s top official at the UN General Assembly, Foreign Minister Wang Yi, sat silently during Trump’s remarks, showing no reaction on camera. Wang is due to speak on US-China relations on Tuesday evening at a business event in New York. China soy purchases The tone of Trump’s speech also was at odds with some recent steps by China to meet his request for purchases of more American farm products. On Monday, Chinese importers bought about 10 shiploads of US soybeans — about 600,000 tons. China’s customs commission will exclude certain amounts of US soybeans, pork and other products from its retaliatory tariffs, the official Xinhua news agency said on Tuesday. The purchases were made following last week’s trade talks, which both the US and Chinese sides characterized as “productive.” People familiar with the trade talks said no new Chinese proposals were presented, and the countries agreed to continue minister-level talks in early October.
