BEIJING, April 11 (Reuters) - China's e-commerce giant

JD.com ( JD ) announced on Friday it will launch a 200 billion yuan

($27.35 billion) fund aimed at helping the country's exporters

sell their products domestically, as a U.S.-China trade war

intensifies.

Beijing on Friday increased its tariffs on U.S. imports to

125%, hitting back against U.S. President Donald Trump's

decision to hike duties on Chinese goods to 145%.
