China's Commerce Ministry said Tuesday that Vice Premier Liu He will be among the delegates visiting Washington to continue trade talks on Thursday and Friday, the Wall Street Journal reported, citing a statement from the ministry. The trip by China's top trade negotiator was at the invitation of U.S. Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin, the ministry said. Lighthizer said Monday that the Trump administration will make good on a threat to raise tariffs on $200 billion in Chinese goods early Friday absent a breakthrough. That threat had been telegraphed on Sunday by a tweeting President Donald Trump, catching investors off guard and triggering risk-off volatility across global markets, which largely continued Tuesday. U.S. stock futures fell in early action after stocks closed lower Monday but had climbed from severe losses, with simmering trade tensions the key factor.
