U.S. stock futures were steady in overnight trade, but Asia benchmarks were sharply lower Wednesday, led by declines in tech stocks.

The South China Morning Post on Wednesday reported the tech sector was leading the way lower in Hong Kong, where Internet giant Tencent fell 2.5%.

The SCMP cited Sam Chi-yung, a senior strategist for South China Securities, as saying reports that Washington is considering a crackdown on Chinese investment in "sensitive" U.S. technologies have refueled concerns about an escalating trade dispute between the two countries.
