In response to Trump's tariffs, Canada and China react.

China: There would be no winners in a trade war with the U.S.

Neither the United States nor China would win a trade war, said the Chinese Embassy in Washington on Monday.

President-elect Donald Trump threatened to implement an additional 10% tariff on all Chinese imports when he takes office in January.

"Regarding U.S. tariffs on China, China believes that economic and trade cooperation between China and the United States is mutually beneficial in nature," said Chinese Embassy spokesperson Liu Pengyu in a statement.

"No one will win a trade war or a tariff war," Liu said.

Trump said he would impose the tariffs until China stops the flow of illegal drugs, particularly fentanyl, into the United States.

In the statement, Liu said that China had taken measures to combat drug trafficking after an agreement was reached last year between President Joe Biden and Chinese President Xi Jinping.

"The Chinese side has notified the U.S. side of the progress made in law enforcement operations related to the United States against narcotics," Liu said.

"All this proves that the idea that China separately allows fentanyl precursors to flow into the United States goes completely against the facts and reality," Liu said.

There have been incremental but visible advances in cooperation on shutting down the illicit trafficking of chemicals used to produce deadly fentanyl after Xi and Biden agreed to resume joint efforts last year.

The United States, where fentanyl abuse has been one of the leading causes of death, has pressured China to do more in law enforcement, including fighting illicit finances and cracking down on new controls over chemicals.

In June, China's top prosecutor urged its law enforcement agents to focus on fighting drug trafficking as Beijing and Washington unveiled a joint drug investigation.

In August, days after a meeting of a joint anti-narcotics task force, China said it would tighten controls on three essential chemicals used to make fentanyl.

Canada and Mexico affected by Trump's tariffs

The measures that the Republican leader wants to implement from his inauguration in January also affect Canada and Mexico, although in these cases with tariffs of 25%. Trump justified them due to crises related to opioids and migration.

Canada stated on Monday that it is "essential for U.S. energy supply" after President-elect Donald Trump announced he would impose new tariffs on its northern neighbor.

"Our relationship is balanced and mutually beneficial, especially for American workers," added Canadian Deputy Prime Minister Chrystia Freeland in a statement, affirming that Ottawa "will continue discussing these issues with the new U.S. administration."

Meanwhile, the President of the Senate of the Republic, Gerardo Fernández Noroña, expressed his response on the social network X to the provisions of the tariff increase that Donald Trump plans to impose on Mexico.
