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.

Trump started hiking tariffs on Chinese goods shortly after his return to the White House. China ultimately responded with tariffs of its own. Tensions escalated, with tariff rates hitting the triple digits, before a trade truce in May.

US and Chinese negotiators wrapped up two days of talks Tuesday without an immediate announcement of a further tariff delay between the world’s two largest economies, but US officials said that still remains an option for President Trump.
