China and the US agree to roll back tariffs in phases, Chinese official says

The tentative agreement sent stocks soaring Thursday.

China's Commerce Ministry spokesman Gao Feng said negotiators between Beijing and Washington have agreed to a "phased cancellation" of tariff hikes if talks continue to progress, the Associated Press reported.

“If the two sides achieve a ‘Phase 1’ agreement, then based on the content of that agreement, tariffs already increased should be canceled at the same time and by the same rate,” Gao said.

On Thursday, a Trump administration official confirmed the accuracy of reports of an agreement to roll back tariffs as part of phase one agreement.

The U.S. and China have leveled billions of dollars of retaliatory tariffs on exports from each other for months, sowing uncertainty for many U.S. businesses.

Earlier this month FitBit announced it would move manufacturing operations out of China to avoid tariffs, joining a growing list of U.S. companies that are doing the same.

Reports that a global trade war could be waning sent stocks soaring Thursday. The S&P 500 jumped to a record-high by midday Thursday and the Dow jumped more than 200 points.

The stocks spike caught the attention of President Donald Trump, who tweeted "Enjoy!"
