Top trade officials from China and the United States have launched a new round of talks aimed at easing tensions over tariffs.

US and China hold crucial trade talks in Stockholm, which will likely extend a 90-day tariff truce and pave the way for a Donald Trump-Xi Jinping summit.

Yet analysts say the Chinese leader is likely holding out for concrete deliverables before agreeing to the high-profile meeting. Trump dramatically escalated the trade war with the world's second-largest economy in April, rolling out sweeping new tariffs that prompted China to respond with its own export duties and other measures.
