French President Emmanuel Macron will travel to south east Asia to pitch France and Europe as reliable partners with "no strings attached" as the U.S. and China use more aggressive ways to gain influence in the region, officials said.

Macron is set to arrive in Hanoi on Sunday, the first trip to Vietnam by a French president in nearly a decade, move on to Indonesia and finish up in Singapore, where he will speak at the annual Shangri-La Dialogue, Asia's top defence conference.

Macron will present France and Europe as defenders of international cooperation and rules-based trade, at a time when other world powers such as the U.S. under President Donald Trump and China use more "coercive" or "predatory" methods.

"As far as we're concerned, we defend the idea of rules for international trade, we don't advocate for the law of the jungle, where it's about survival of the fittest," a French presidential adviser said on Wednesday.
