Japanese Finance Minister Katsunobu Kato drew attention by mentioning that the country’s more than $1.1 trillion in U.S. Treasury bonds could potentially be a “card on the table” in negotiations with Washington over Trump’s steep tariffs on autos and other imports.

Late Thursday, technology behemoths Amazon and Apple reported their latest results. Shares of Apple fell about 3% overnight after the iPhone company beat Wall Street expectations but forecast an additional $900 million to its costs in the current quarter as a result of the tariffs, if they remain in place as announced.

Officials in Beijing said they want the Trump administration to “show sincerity,” as it evaluates efforts by the U.S. to start trade negotiations.
