MOSCOW, Nov 13 — Russian Foreign Minister Sergei Lavrov today said the West was "militarising” South-east Asia in a bid to contain Russian and Chinese interests, setting the stage for a confrontation between Russia and Western leaders at the G20 summit in Bali.

Lavrov will head Russia’s delegation to the summit - the first such meeting since Moscow invaded Ukraine in February - after the Kremlin said President Vladimir Putin was too busy to attend.

Ukraine is set to dominate the agenda with Western leaders likely to publicly confront Russia over its invasion of Ukraine and push the likes of China and India - which have both previously expressed concerns over the war - to criticise Moscow’s actions.

Speaking during a press conference at the conclusion of the Association of Southeast Asian Nations (Asean) summit in Phnom Penh, Lavrov scolded the United States over its actions in the region, which both Russia and the West see as a potential strategic geopolitical battleground in the coming decades.

"The United States and its Nato allies are trying to master this space,” Lavrov told reporters.

He said Joe Biden’s Indo-Pacific strategy was an attempt to bypass "inclusive structures” for regional cooperation and would involve "the militarisation of this region with an obvious focus on containing China, and containing Russian interests in the Asia-Pacific.”

Biden told southeast Asian leaders that Washington was committed to building an "Indo Pacific that’s free and open, stable and prosperous, and resilient and secure” as he outlined a Comprehensive Strategic Partnership between the United States and the region.

Neither the United States nor Russia is a member of Asean, a 10-member group of southeast Asian countries, but several world leaders attended the talks ahead of next week’s G20 summit in Bali.

Russia has sought to foster much closer economic, political and security ties with Asia since the West hit Moscow with unprecedented sanctions in response to the invasion of Ukraine.
