O TTAWA—Canadian Prime Minister Mark Carney said bilateral talks with Washington to resolve the tariff row might not lead to a deal before the Aug. 1 deadline. Senior officials are in Washington to find an agreement that is suitable for Canada, Carney said.

The United States and China have agreed to work on extending a deadline for new tariffs on each other after two days of trade talks in Stockholm concluded on Tuesday, according to Beijing’s lead negotiator.

The U.S. and China had agreed to pause most of the sky-high tariffs on each others’ goods amid trade negotiations – but that pause is set to expire in August.
