US media have reported that Canadian Prime Minister Justin Trudeau has arrived in the southern US state of Florida for talks with President-elect Donald Trump. His visit follows Trump's recent pledge to impose new tariffs on Canada and Mexico.

On Monday, Trump said on social media that upon his inauguration on January 20, he will sign documents as one of his first executive orders to impose a 25-percent tariff on all products from the two countries.

He claimed that crime and drugs are being brought into the US through Mexico and Canada "at levels never seen before."

US media say Trudeau flew to Florida on Friday to meet with Trump at his Mar-a-Lago residence. The Associated Press quoted a person familiar with the matter as saying Trudeau will have dinner with Trump.

The Canadian government has yet to release any official comments.

Mexican President Claudia Sheinbaum was also reported to have held talks with Trump. In a social media post on Wednesday, she said they had an "excellent" conversation.
