LONDON — Two of the world’s biggest trading blocs are cautiously eyeing closer ties to short-circuit Donald Trump’s tariffs.

The European Union and a 12-nation Indo-Pacific bloc are opening talks to explore proposals to form one of the largest global economic alliances, multiple people with knowledge of the talks told POLITICO.

Canada is spearheading the discussions after Prime Minister Mark Carney called on middle powers to buck trade war coercion last month, days after Trump threatened to raise tariffs on Denmark’s European allies if it didn’t cede Greenland.

Ottawa is “championing efforts to build a bridge between the Trans-Pacific Partnership [CPTPP] and the European Union, which would create a new trading bloc of 1.5 billion people,” Carney told world leaders and the global business elite in Davos.
