Trump Withdraws Invitation for Carney to Join Peace Board

The notification comes after the two criticized each other’s comments on US–Canada and international relations in public speeches this week.

U.S. President Donald Trump has withdrawn his administration’s invitation for Canadian Prime Minister Mark Carney to join the U.S.-led Board of Peace that will initially focus on rebuilding Gaza.

“Please let this Letter serve to represent that the Board of Peace is withdrawing its invitation to you regarding Canada’s joining, what will be, the most prestigious Board of Leaders ever assembled, at any time,” Trump said in a post on Truth Social addressed to Carney late on Jan. 22. “Thank you for your attention to this matter!”

The notification comes after the two criticized each other’s comments on U.S.–Canada and international relations in public speeches this week.

In a speech at the World Economic Forum (WEF) in Davos, Switzerland, on Jan. 20, Carney criticized U.S. pressure to take over Greenland, and called for countries to not comply with “great powers,” saying the rules-based international order has undergone a “rupture.” He urged middle powers to band together to resist pressure from major powers, without specifying who the major powers are or making any distinctions.

“Great powers have begun using economic integration as weapons, tariffs as leverage, financial infrastructure as coercion, supply chains as vulnerabilities to be exploited,” he said. “You cannot live within the lie of mutual benefit through integration, when integration becomes the source of your subordination.”

His comments came amidst increasing U.S. protectionist measures and days after his visit to China, where he said a new strategic partnership with Beijing sets “us up well for the new world order.”

In his own speech at the WEF on Jan. 21, Trump said that he listened to Carney’s speech and that the Canadian prime minister “wasn’t so grateful,” adding that Canada “lives because of the United States.”

“Canada gets a lot of freebies from us, by the way, they should be grateful also, but they’re not,” Trump said. “Canada lives because of the United States. Remember that, Mark, the next time you make your statements.”

A day later in a speech addressed to Canadians on Jan. 22, Carney rebuked Trump’s remarks, saying Canada “does not live because of the United States. Canada thrives because we are Canadian.”

Also on the same day, U.S. Commerce Secretary Howard Lutnick said Ottawa could risk jeopardizing the upcoming renegotiations of the United States-Mexico-Canada Agreement (USMCA) by seeking closer relations with China. He suggested that Canada’s decision to open its market to Chinese electric vehicles (EVs) amounts to going down a “political path,” and may have an adverse impact on its free-trade relations with the United States, which he said is the “second-best deal” in the world after Mexico. During his trip to China, Carney agreed to cut tariffs on Chinese EVs from 100 percent to 6.1 percent for the first 49,000 imported units, in exchange to Beijing cutting tariffs on Canadian canola from 85 percent to 15 percent until at least the end of 2026.

Trump’s Board of Peace of inaugurated earlier on Jan. 22, with representatives from 19 nations joining Trump at the WEF for the official launch of the initiative. The founding members of the board taking part in the official launch were for the most part from Asia, save for close Trump allies such as Argentina and Hungary.

Western European leaders and Russian President Vladimir Putin have also been invited to join, but they haven’t yet officially accepted the invitation.

Carney said last week that he had agreed in principle to join the Board of Peace, adding that details such as financing still need to be worked out. Canada’s Finance Minister François-Philippe Champagne said this week that Ottawa had no intention of paying $1 billion to join the board, an amount a U.S. official had cited as the entry fee, which would be used to help Gaza.

Carney was the only leader Trump publicly informed that the invitation to join had been rescinded.
