BEIJING - A spokesperson for China's Ministry of Public Security on Sunday expressed strong dissatisfaction with and firm opposition to the US decision to impose a 10 percent additional tariff on imports from China under the pretext of fentanyl-related issues.

China is one of the countries with the strictest drug control policies and the most rigorous enforcement in the world, said the spokesperson, adding that China has consistently and resolutely fulfilled its international drug control obligations and actively engaged in international anti-drug cooperation with countries around the world, including the United States.

Despite the absence of widespread abuse domestically, China became the first country in the world to officially schedule fentanyl-related substances as a class in 2019 out of humanitarian goodwill and at the request of the US side, said the spokesperson. However, the United States has not scheduled fentanyl-related substances as a class on a permanent basis.

Since China's regulation, there have been no reports from the United States of seizures of such substances originating from China, added the spokesperson.

In recent years, China and the United States have made visible progress in practical cooperation on drug control in such areas as substance regulation, intelligence exchange, and case cooperation, producing tangible benefits, according to the spokesperson.

The spokesperson noted that the root cause of the fentanyl crisis in the United States lies in itself, and reducing domestic drug demand and strengthening law enforcement cooperation are the fundamental solutions.

Shifting blame onto other nations not only fails to resolve the issue but also erodes the foundation of trust and cooperation in the field of drug control between China and the United States, said the spokesperson.

China urges the United States to correct its wrongdoings and safeguard the hard-won progress in bilateral drug control cooperation, so as to promote the stable, healthy, and sustainable development of China-US relations, the spokesperson said.

Meanwhile, the China Council for the Promotion of International Trade (CCPIT) said China's business community deeply regrets and firmly opposes the US decision.

The US unilateral imposition of additional tariffs seriously violates World Trade Organization (WTO) rules, and many US businesses and consumers will have to bear the costs, a CCPIT spokesperson said in a statement.

This move will disrupt normal China-U.S. economic and trade cooperation and threaten the stability of global industrial and supply chains, the spokesperson added.

"There is no winner in trade and tariff wars," the spokesperson stressed, noting that the erroneous actions by the United States will not solve the US problems at home. Instead, they will harm China-US relations and negatively affect global economic development.

China's business community has urged the US side to immediately correct its wrongdoings, work with China to meet each other halfway, and strengthen cooperation with other countries to foster a favorable international environment for mutual benefit and win-win outcomes for the business communities of both countries and the world, and to inject more stability and positive energy into the global economy, the spokesperson said.
