China has made proposals in talks with the United States on a range of issues that go further than it has before, including on forced technology transfer, as the two sides work to overcome obstacles to a deal to end their protracted trade war, reports Reuters, citing US officials.

U.S. President Donald Trump imposed tariffs on $250 billion of Chinese imports last year in a move to force China to change the way it does business with the rest of the world and to pry open more of China’s economy to U.S. companies.

Among Trump’s demands are for Beijing to end practices that Washington alleges result in the systematic theft of U.S. intellectual property and the forced transfer of American technology to Chinese companies.

Trump said last week the United States may leave tariffs on Chinese goods for a “substantial period” to ensure compliance.
