Both European stocks and US equity-index futures reversed earlier gains to trade lower by mid-afternoon in London, as investors eyed a move by the US to add 28 Chinese entities to an export blacklist.

The Commerce Department unveiled the blacklist late on Monday, targeting China-based tech companies operating in the artificial intelligence space that were deemed to have been "implicated in human rights violations”, citing their role in Beijing’s repression of Muslim minorities in northwest China.

Foreign Ministry spokesman, Geng Shuang, said the United States is interfering in his country's internal affairs.

The censure, which has sparked fears of reprisal against US companies by Beijing, comes just three days before China’s top trade envoy, Liu He, will lead a delegation to resume trade talks with Washington.

These development look to extend upon Monday’s decline, where Wall Street ended red, having spent most of the session fluctuating between gains and losses as investors refocused their attention to trade.

The S&P 500 shed -0.43% of its value, with Communications Services (0.00%) being the only major sector to end in the black, while Energy (-0.89%) led the declines. The Nasdaq Composite ended -0.30% lower.

Ahead, in today’s economic calendar, Tuesday includes; the Producer Price Index for September at 8:30am EST, followed by Federal Reserve Chairman, Jerome Powell’s, scheduled speech at the 61st National Association of Business Economics Annual Meeting at 1:50pm EST.
