U.S. stock indexes traded lower Thursday noon following some conflicting developments with China. While China’s top trade negotiator called for a new round of trade talks, the U.S. Congress passed a bill that supports Hong Kong protesters.

The Dow Jones Industrial Average dropped 82.94 points to 27,738.15 while the S&P 500 lost 9.34 points to 3,099.12 and the Nasdaq Composite Index dropped 36.72 points to 8,490.01.

The Wall Street Journal reported Chinese Vice Premier Liu He invited U.S. Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin to hold a meeting in Beijing for new trade talks.

Bloomberg reported Liu was “cautiously optimistic” about reaching a phase one trade deal.

However, China is likely upset by passage in the U.S. Congress late Wednesday of a bill that endorses the pro-democracy protesters in Hong Kong and requires the U.S. to scrutinize Hong Kong’s special trade status. The U.S. Senate had earlier passed the same bill. It was to go to President Trump Thursday.

Traders also digested a slew of mixed economic data.

The Philadelphia Fed manufacturing index rose to a seasonally adjusted reading of 10.4 in November, up from 5.6 in October. Economists had expected a reading of 7 for November.

Minneapolis Fed President Neel Kashkari said he is not expecting the economy to slide into recession. “Right now overall my base case scenario is continued economic growth,” he said at the Minnesota Chamber of Commerce. “But there are risks on the horizon, the biggest risks being around tariffs and trade and the uncertainty that creates.”
