Amid Trump’s trade war blitz, any tariff pause extension between the US and China will need the US president’s approval.

China’s top leaders have pledged to help companies slammed by higher U.S. tariffs but held back on major moves after trade talks.

U.S. and Chinese officials agreed to seek an extension of their 90-day tariff truce on Tuesday, following two days of what both sides described as constructive talks in Stockholm aimed at defusing an escalating trade war between the world's two biggest economies that threatens global growth.
