WASHINGTON -- Preserving US-China phase-one trade agreement would bring stability for the commercial relationship, a US business leader said Wednesday, urging the Joe Biden administration to fully implement the deal.

"While it doesn't address every issue in the commercial relationship, the US-China phase-one agreement made important progress on longstanding trade barriers," US-China Business Council (USCBC) President Craig Allen told reporters at a virtual press conference Wednesday afternoon.

"I would say that the best options for the Biden administration would be simply to preserve and fully implement phase one (trade deal), fast track phase two (negotiations)," said Allen, warning that withdrawing from the phase-one trade deal would benefit no one.

Noting that tariffs imposed amid US-China trade frictions remain in place, Allen said tariffs going both ways have harmed American jobs, American consumers, American companies and the country's global competitiveness.

"Both sides have been hurt and removing the tariffs are important," he said. "The best remedy for boosting trade and creating more US jobs is for both the United States and China to permanently remove tariffs."

According to the 2021 State Export Report newly released by the USCBC, US goods exports to China in 2020 surged by $18.5 billion -- up almost 18 percent year-on-year -- after hitting a near-decade low in 2019 amid the US-China trade tensions.

The boost was made possible by huge shipments of agriculture products, semiconductors, and oil and gas products, the report showed, noting that US exports to China made a comeback in 2020 as phase-one deal bolstered trade.

Allen noted that China's temporary tariff exemptions for US imports, market openings under the phase-one trade deal, as well as strong demand amid China's robust recovery have contributed to the surge in the US goods exports to China.

"These exports mean support for American businesses and families, which could not be more important right now," said Allen, whose trade association represents over 200 American companies doing business with China.

In 2019, the latest year of available data, services exports to China -- which include travel, education, and financial services -- dropped by $1.7 billion, or 3 percent, according to the USCBC.

Despite data lags, Allen said it's "highly likely" that US services exports to China in 2020 saw a severe decline amid the COVID-19 pandemic, considering the grim situation in travel and education.

In response to a question from Xinhua, Allen said he is hopeful that the decline in US education exports to China last year is only COVID-19 related, "but we shouldn't take that for granted."

"I think that American universities and colleges should really be marketing heavily in China," said Allen, adding that with a growing middle class, many of the young people in China are seeking to travel and study abroad, and American universities and colleges remain attractive for them.

"So I'm hopeful that we will not see a dip after the COVID-19 is over," he said.
