The United States is proposing a new round of high-level trade talks with China, the Wall Street Journal reported Wednesday, at a time when President Donald Trump threatens to impose tariffs on additional Chinese imports.

The Trump administration has suggested holding the talks "in the coming weeks" and asked China to dispatch a ministerial delegation for a meeting that might take place in Washington or Beijing, the paper said, quoting people briefed on the matter.

Senior U.S. officials, led by Treasury Secretary Steven Mnuchin, sent an invitation this week to Chinese counterparts headed by Vice Premier Liu He, it said.

The proposal -- which would give Beijing an opportunity to address U.S. concerns about its "unfair" trade practices -- comes as Trump threatens to slap levies on an additional $200 billion of Chinese imports.

Trump suggested he could do more to push for changes in Beijing's alleged intellectual property and technology theft.

The administration has imposed duties on a total of $50 billion in Chinese goods, with Beijing retaliating with tariffs on an equal value of U.S. goods.

Including the additional $200 billion worth of Chinese products, the United States would be taxing about half of the goods it imports from China each year.
