Wall Street was set for gains, with the future for the Standard & Poor's 500 index up 0.4 percent, while the same measure for the Dow Jones Industrial Average advanced 0.5 percent. The Shanghai Composite Index rose 5.6 percent to 2,961.28, its highest close since June 15, and Trump said the negotiations in Washington made "substantial progress."
Trump said he would postpone a March 1 deadline for 10 percent punitive tariffs on $200 billion of Chinese imports to rise to 25 percent but set no new date. The world's two biggest economies have raised tariffs on billions of dollars of each other's goods in the fight over U.S. complaints Beijing steals or pressures companies to hand over technology.
Washington wants China to roll back plans for government-led creation of global competitors in robotics and other technologies. Europe, Japan and other trading partners echo U.S. complaints those violate Beijing's free-trade obligations.
The fight threatens to disrupt global trade and weigh on economic growth that shows signs of faltering. Investors also are watching February manufacturing indicators due out this week for signs of further deceleration in global activity.
Trump's announcement should reassure financial markets, but stock gains outside of China might be limited because prices already had risen in expectation of such a move, analysts said. "The latest news may not offer a significant boost to start the week," Tai Hui of J.P. Morgan Asset Management said in a report. "Nonetheless, it helps to underpin positive investor sentiment."
Tokyo's Nikkei 225 advanced 0.5 percent to 21,528.23 while Hong Kong's Hang Seng added 0.5 percent to 28,959.30. Seoul's Kospi gained 2 points to 2,232.56. India's Sensex advanced 0.5 percent to 35,950.50 and Sydney's S&P-ASX 200 rose 0.3 percent to 6,186.30. New Zealand, Taiwan and Southeast Asia advanced.
