(Reuters) – U.S. stock index futures slipped on Tuesday after President Donald Trump said a trade deal with China might have to wait until after the U.S. presidential election in November 2020, sparking fears of a delay in resolving the tariff dispute. “I have no deadline, no. In some ways I think it’s better to wait until after the election with China,” Trump told reporters in London where he was due to attend a meeting of NATO leaders. Technology stocks including Apple Inc (AAPL.O) as well as chipmakers and industrial stocks, which are trade-sensitive, fell in premarket trading. Most U.S.-listed Chinese stocks were also trading lower. The prolonged dispute between the world’s top two economies has roiled financial markets, disrupted supply chains and dented global growth. The latest fallout of the trade war on the domestic economy was dismal factory activity data, which led Wall Street’s main indexes in the previous session to pull back from their record highs.
