Beijing is prepared to engage in a slugging match, but its preferred solution to the deepening trade dispute remains a diplomatic outcome, analysts said.
"This is a negotiating tactic," said Jeff Moon, a former US assistant trade representative for China. "They tried negotiating by hinting at concessions. This is hinting at the sharp end of the stick."
China also is being careful to act within the rules of the global trading system that were established under US leadership over the past seven decades. As it broadens its global role, Beijing is eager to portray itself as a responsible actor in contrast to a rogue US that is withdrawing from treaties and shunning multilateral cooperation.
China's measured response thus far is meant to show that "they stand on the moral high ground here," said Claire Reade, a former US trade negotiator now with Arnold & Porter.
Chinese officials previewed their US$3 billion action in public comments on March 23, one day after Trump announced that he intended to impose tariffs on up to US$60 billion in imported Chinese products, including aerospace, information technology and machinery.
But Chinese officials billed their tariffs as a response to Trump's earlier import levies on steel and aluminum. Like the European Union, which also objected to Trump's metals tariffs, the Chinese rejected the President's claim that his actions on steel and aluminum were justified by national security considerations.
Instead, China and the EU said the United States had acted on economic grounds, seeking to protect its industries from an unwelcome flood of imported products. In that event, under the rules of the World Trade Organisation, China was authorised to retaliate.
"US unilateralism allows China to play the victim," said one trade lawyer.
The products that China has selected for retaliation also are not essential to its role in the global supply chain. Raising the cost of imported dried fruit won't affect Chinese factories that make cars for General Motors or smartphones for Apple.
The next movein the Sino-US trade fight will be the US trade representative's publication of the roughly 1300 separate tariff lines it intends to increase as part of a separate action in response to China's policy of forced technology transfer.
Expected soon, that list will trigger a 30-day comment period before the tariffs are finalised. China's eventual response will probably remain within WTO bounds and leave room for talks between the two sides, Moon said.
Darci Vetter, a former US trade negotiator, said that American farmers will probably bear the brunt of any additional rounds of Chinese tariff increases. China last year purchased US$19.6 billion in agricultural goods from the United States, ranking it second in foreign markets.
"You saw them react to steel and aluminum. Within the next week, we'll see bigger [US] tariffs. We should expect to see retaliation for that as well," she said. "Ag is in the crosshairs."
Chinese bureaucrats have a range of powers they can exercise to slow or discourage the movement of US products into their country without running afoul of WTO norms. Health inspections, paperwork delays and routine trade remedy cases all may proliferate.
"What they've put out so far isn't the worst they could do," said Christine McDaniel, a former trade economist in the George W. Bush Administration.
