Chinese Premier Li Keqiang appealed to Washington on Tuesday to "act rationally" and avoid disrupting trade over steel, technology and other disputes. He promised Beijing will "open even wider" to imports and investment.

"No one will emerge a winner from a trade war," said Li, the No. 2 Chinese leader, at an annual news conference held during the meeting of China's ceremonial legislature.

Li made no mention of a possible Chinese response if U.S. President Donald Trump raises import barriers over trade complaints against Beijing. But other officials say President Xi Jinping's government is ready to act.

Now, Mr. Trump is reportedly considering tariffs on up to $60 billion of Chinese goods following an investigation into China's trade practices. The tariffs could cover a wide range of imported goods: electronics; apparel and footwear; transportation equipment tied to planes, ships and rail. U.S. business groups have warned that might hurt American companies and consumers, while some fear Beijing might retaliate by cutting Chinese purchases of American jetliners, soybeans and other goods.

"Beijing will not want to be seen as being soft vis-a-vis the U.S. Its response will surely include strong protests, and probably also some trade measures targeting the U.S.," wrote Louis Kuijs, head of Asia economics at Oxford Economics, in a research note. "Another possibility would be to exert pressure on US businesses in China by means of further inspections, tests and delays in procedures."

Li said China doesn't want a trade war. "What we hope is for us to act rationally rather than being led by emotions," he said.

Commerce Minister Zhong Shan said on March 11 that China will "resolutely defend" its interests.

Asked whether Beijing might use its large holdings of U.S. government debt as leverage, the premier said its investments are based on market principles and "China will remain a responsible long-term investor."

China and the United States have one of the biggest global trading relationships but the flow is lopsided. Americans buy Chinese goods worth $3 for every $1 of goods they sell to China.

Beijing reported a trade surplus of $275.8 billion with the United States last year, or two-thirds of its global total. Washington reports different figures that put the gap at a record $375.2 billion.

Li promised more market-opening and other reforms as Xi's government tries to make its cooling, state-dominated economy more productive. He said Beijing will make it easier to start a business and will open more industries to foreign and private competition.

The ruling Communist Party promised in 2013 to give a bigger role to market forces and entrepreneurs who generate most of China's new jobs and wealth.

Reform advocates complain they are moving too slowly, but hope Xi, who took power in 2012, might accelerate changes after focusing during his first five-year term as party leader on cementing his status as China's most dominant figure since at least the 1980s.

"If there is one thing that will be different from the past, that will be that China will open even wider," said Li.

Beijing plans to "further bring down overall tariffs," with "zero tariffs for drugs, especially much-needed anti-cancer drugs," the premier said.

Li repeated a promise he made March 5 at the opening of the legislature to "fully open the manufacturing sector" to foreign competitors.

"There will be no mandatory requirement for technology transfers and intellectual property rights will be better protected," the premier said.

The government has yet to say how that might change conditions for automakers and other manufacturers. Under current rules, those that want to operate in China are required to work through local partners, which requires them to give technology to potential competitors.

In a sign of Li's reduced status as Xi amasses power, the premier was flanked by four new vice premiers and four other economic officials, in contrast to previous years when he appeared alone at the annual news conference.

They included Liu He, a Harvard-trained Xi adviser who was named a vice premier Monday and has told foreign businesspeople he will oversee economic reform. Neither Liu nor any of the other officials spoke at the event.

The premier traditionally is China's top economic official but Xi has stripped Li of his most prominent duties by appointing himself to lead ruling party bodies that oversee economic reform and finance policy.
