WASHINGTON--The Trump administration is dropping its designation of China as a currency manipulator in advance of the signing Wednesday of a Phase 1 U.S.-China trade agreement.

The preliminary pact that the two sides are set to sign this week includes a section that's intended to prevent China from manipulating its currency to gain trade advantages.

The action announced Monday comes five months after the Trump administration had branded China a currency manipulator--the first time that any country had been so named since 1994 during the Clinton administration.

Even while removing China from its currency black list, the Treasury Department does name China as one of 10 countries it says require placement on a watch list that will mean their currency practices will be closely monitored. In addition to China, the countries on that list are Germany, Ireland, Italy, Japan, South Korea, Malaysia, Singapore, Switzerland and Vietnam.

Treasury Secretary Steven Mnuchin said the administration had dropped China’s designation as a currency manipulator because of commitments in the Phase 1 trade agreement that President Donald Trump is to sign with China on Wednesday at the White House.

“China has made enforceable commitments to refrain from competitive devaluation, while promoting transparency and accountability,” Mnuchin said in a statement accompanying the currency report.

Some critics of China's trade practices criticized the administration's decision Monday.

“China is a currency manipulator--that is a fact,” said Sen. Chuck Schumer of New York, the Democratic leader in the Senate. “When it comes to the president's stance on China, Americans are getting a lot of show and very little results.'”

The Treasury Department is required to report to Congress twice a year in April and October on whether any countries are manipulating their currencies to gain unfair trade advantages against U.S. businesses and workers. When a country manipulates its currency to keep it artificially low, its goods become comparatively less expensive overseas--and other countries' goods become relatively more expensive.

The new report is technically three months late, apparently because the Trump administration had delayed its release until it had achieved the currency Phase 1 commitments from China.

The initial decision to brand China as a manipulator had come in a surprise announcement in August, reversing a Treasury finding in May that no country was manipulating its currency. The United States had not put any country on the manipulation blacklist since the Clinton administration branded China a manipulator 26 years ago. Trump had long accused China of manipulating its currency, even though most independent experts concluded that Beijing had stopped doing so years ago.

The designation was largely symbolic. It obliged the United States to enter into negotiations to resolve the currency problem that could ultimately lead to the imposition of economic sanctions such as higher tariffs on Chinese goods--something the Trump administration was already doing in its tit-for-tat trade war with China.

Trump is scheduled to sign the Phase 1 agreement on Wednesday after which administration officials said the text of the deal will be made public.

In a fact sheet on the deal released Dec. 13, the administration said the agreement would address ‘"unfair currency practices by requiring high-standard commitments to refrain from competitive devaluations and targeting of exchange rates."’

The signing of the Phase 1 agreement caps a rocky two-years of trade conflict between the two nations in which punitive tariffs were imposed on billions of dollars of products from each nation. The battle escalated uncertainty and caused businesses to pull back on their investments, slowing global growth. It also roiled financial markets with fears that the trade war could become serious enough to push the U.S. economy into a recession.
