The Wall Street Journal reported the Trump administration plans to impose curbs on Chinese investment in American technology companies and high-tech exports to China. The newspaper, citing unidentified sources, said the initiatives were aimed at preventing Beijing from moving ahead with plans to develop global competitors in technologies including biotech and electric vehicles. That follows President Donald Trump's threat to hike tariffs on Chinese imports worth up to $450 billion over complaints Beijing steals or pressures foreign companies to hand over technology.

In a tweet, Treasury Secretary Steven Mnuchin denied that any such initiatives would be aimed solely at China.

On behalf of @realDonaldTrump, the stories on investment restrictions in Bloomberg & WSJ are false, fake news. The leaker either doesn’t exist or know the subject very well. Statement will be out not specific to China, but to all countries that are trying to steal our technology. — Steven Mnuchin (@stevenmnuchin1) June 25, 2018

Beijing freed up about $100 billion for additional bank lending in a move financial analysts said might help reassure investors rattled by trade tensions with Washington. The cut in the amount of money banks are required to hold in reserve, the second this year, is one of a series forecasters had expected before the dispute over China's trade surplus and technology policy erupted. The central bank said the move is aimed at facilitating debt-for-equity swaps meant to help clear away a backlog of nonperforming bank loans owed by state companies.
