Russia's veteran diplomat and current ambassador to the United States, Alexander Darchiev, has passed away suddenly at the age of 66. The Russian Foreign Ministry announced his demise on Wednesday without providing further details about the cause or circumstances of his death. Darchiev had served in one of the most critical areas of Russian foreign policy and was a specialist in Russia-US relations. He joined diplomatic service in 1992, eventually becoming the head of North America department in Russia's Foreign Ministry and serving as an adviser to the Russian Embassy in the US from 1997 to 2010. Darchiev was also Russia's ambassador to Canada between 2014 and 2021, returning to the North America department as its director in 2010 and later holding the post again until last year. His tenure as ambassador to the US began in March 2021, shortly after US President Donald Trump returned to power and several years into Moscow's full-scale invasion of Ukraine. Notably, Darchiev was born into a diplomatic family and had previously served as Russia’s ambassador to Canada for seven years before returning to the Foreign Ministry in 2021.

In his capacity as Russia's ambassador to the US, Darchiev called Russia's offensive against Ukraine a "necessary measure" when it was launched in 2022. His diplomatic career spanned over three decades and he had held various positions within the Foreign Ministry, including first secretary and head of North America department. He also served as an adviser to the Russian Embassy in the US and minister-counsellor from 2005 to 2010. The Russian Foreign Ministry paid tribute to Darchiev, describing him as an "outstanding diplomat, an experienced leader, and a kind colleague."

The sudden passing of Alexander Darchiev has left a void in the Russia-US diplomatic relations, as he was an important figure in shaping these relations. His death comes at a critical time in US-Russia relations, as both countries navigate various geopolitical challenges and ongoing conflicts. The cause of his death remains unknown, but his contributions to Russian foreign policy will be remembered for years to come.
