Representatives of the United States and several other countries have walked out of an Asia-Pacific trade ministers meeting in Bangkok to protest Russia’s invasion of Ukraine, officials and diplomats say.

Representatives from Canada, New Zealand, Japan, and Australia joined the Americans in walking out of the Asia-Pacific Economic Cooperation (APEC) meeting on May 21, two Thai officials and two international diplomats said.

The walkout took place while the Russian representative was delivering remarks at the opening of the two-day meeting of the group of 21 economies.

Another diplomat told Reuters the five countries that staged the protest wanted “stronger language on Russia’s war” in the group’s final statement to be issued on May 22.

World leaders have strongly condemned Russia’s unprovoked war on Ukraine that was launched on February 24.

In past weeks, the European Union, the United States, and several other Western allies have also slapped sanctions on Russian President Vladimir Putin, the Russian economy, and many of the country’s billionaires.
