State media shrugged off US President-elect Donald Trump's pledge to slap additional tariffs on Chinese goods in editorials late on Tuesday, accusing him of blaming China for the country's failure to address the fentanyl crisis.

Trump, who takes office on January 20, said on Monday that he would impose "an additional 10 percent tariff, above any additional tariffs" on imports from China.

Editorials in the China Daily and the Global Times focused squarely on the reason Trump gave for imposing the tariffs: fentanyl.

China Daily said scapegoating others cannot end the drug crisis in the US while the Global Times urged Washington not to take China's goodwill for granted regarding anti-drug cooperation, after Trump's remarks.

"The excuse the president-elect has given to justify his threat of additional tariffs on imports from China is far-fetched," China Daily said.

"The world sees clearly that the root cause of the fentanyl crisis in the US lies with the US itself.

"There are no winners in tariff wars. If the US continues to politicise economic and trade issues by weaponising tariffs, it will leave no party unscathed."

Trump on Monday also pledged 25 percent tariffs on goods coming from Mexico and Canada until they clamp down on drugs and migrants crossing the border.

Canadian Prime Minister Justin Trudeau said he had a "good" conversation with Trump immediately following the president-elect's announcement.

"We talked about how the intense and effective connections between our two countries flow back and forth," as well as "some of the challenges that we can work on together," Trudeau told reporters in Ottawa.

The Canadian leader has assembled a team of ministers to lobby US lawmakers and members of Trump's inner circle, a repeat of a charm offensive during his first term as president.

Meanwhile, Mexican President Claudia Sheinbaum suggested on Tuesday that Mexico could retaliate with tariffs of its own.

Sheinbaum said she was willing to engage in talks on the issues but said drugs were a US problem. (Agencies)
