President Donald Trump is back in the U.S. after two days of talks with President Xi Jinping in Beijing that saw both sides trade praise and tout progress in stabilizing what they agreed is the world’s most important relationship.

The president hailed “fantastic” trade deals and said “a lot of different problems” were settled, though no major agreements or breakthroughs were announced before he departed Beijing.

Xi warned Trump on Day 1 of the summit that mishandling China’s claims on Taiwan could cause “clashes and even conflicts,” with the disputed island central to Beijing’s view of the talks. En route to Alaska after the summit, Trump said he has not made a decision on whether to proceed with a $14 billion arms sale to the democratic island.

The U.S. assessments focused on trade and Iran. Trump discussed the Iran war and the blockade of the Strait of Hormuz with Xi, Secretary of State Marco Rubio told NBC News, adding that Trump did not ask Xi for help in ending the monthslong war.
