BEIJING (Reuters) - China's state media have praised some U.S. firms for "strong collaboration" - commentary that comes amid fears of a trade war and is reminiscent of how tensions with the U.S. were covered by Chinese newspapers during Donald Trump's first presidency.

Trump, who takes office on Jan. 20, said on Monday he would impose a 10% tariff on Chinese goods so that Beijing does more to stem the flow of Chinese-made chemicals powering an opioid epidemic in the United States.

He has also threatened tariffs in excess of 60% on Chinese goods while on the campaign trail.

During Trump's first term, corporate executives and foreign investors scoured Chinese state media for signals as to which U.S. firms might be in favour and which might be penalised as trade tensions ratcheted up.

The state-owned Global Times late on Wednesday praised Apple ( AAPL ), Tesla, Starbucks ( SBUX ) and HP for strong collaboration with Chinese partners.

"U.S. politicians need to pay attention to and respect the evident willingness of American businesses for economic and trade cooperation by tailoring suitable policy environments for enterprises," it said.

The China Daily also noted that Morgan Stanley ( MS ) received regulatory approval in March to expand its China operations, citing this as evidence of foreign financial firms' enthusiasm for investing in China.

During Trump's first term, Chinese authorities did not often make direct official comments on the trade war.

Authorities in mainland China this week have yet to make direct comment on the 10% tariff promised by Trump, although a Chinese embassy official in Washington has said no one will win a trade war.

Only 47% of U.S. firms were optimistic about their five-year China business outlook, a September survey by the American Chamber of Commerce in Shanghai showed.
