—Asian stock markets mostly advanced Tuesday after President Trump unveiled his three-week extension to negotiate trade agreements, spurring mild hopes for deals following punishing U.S. tariffs. Japan’s Nikkei 225 index gained 0.3%, and Hong Kong’s Hang Seng gained 1%. China’s benchmark Shanghai Composite gained 0.7%.

What level of tariffs will the U.S. impose on imports and when? Stock futures were falling early Monday as markets were roiled by threats of new levies but also confusion over the deadline for the proposed duties.

Japan, South Korea, Malaysia and Kazakhstan will face 25% import duties starting Aug. 1, while goods from Laos and Myanmar will face a 40% tariff.
