President Trump and Chinese leader Xi Jinping spoke on Thursday, and both countries pledged to restart tariff and trade talks in the coming days. Trump hailed the call as "positive," with both leaders inviting the other to visit their respective countries.

It’s hard to know if Trump's comments on Xi Jinping suggest the world’s two biggest economies are getting any closer to a deal on tariffs.

Earlier this week, China hit back on Trump’s claims the Asian country was in breach of a new trade agreement, struck last month following talks held in Geneva, Switzerland, countering that the U.S. itself was undermining the deal with new sanctions.
