—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%.

Stock markets slipped in Asia amid much confusion as U.S. officials flagged a delay on tariffs but failed to provide any detail or paperwork on the change, while oil prices slid as OPEC+ opened the supply spigots more than expected.

Asian shares opened cautiously as investors held back from taking risky bets after President Donald Trump ruled out extending his August deadline. Copper futures fell on Trump’s tariff threat.
