Vitaly Churkin, who served as Russia's permanent representative to the United Nations since 2006, "died suddenly" in New York, the Russian Foreign Ministry announced. Churkin died one day before his 65th birthday. Russia's deputy U.N. ambassador, Vladimir Safronkov, told AP that Churkin became ill and was taken to Columbia Presbyterian Hospital, where he died Monday.
Churkin was at the Russian embassy on East 67th Street when he became sick with a “cardiac condition” around 9:30 am, sources told the New York Post. A Russian Embassy spokesperson told CBS News that they believe Churkin died of a heart attack but they do not yet have official word on the cause of death.
As the AP adds, Churkin has been Russia's envoy at the United Nations for a little over a decade and was considered Moscow's great champion at the U.N. He had a reputation for an acute wit and sharp repartee especially with his American and Western counterparts. He was previously ambassador at large and earlier served as the foreign ministry spokesman.
Colleagues took to social media to react to Churkin’s death, starting with Churkin's old nemesis Samantha Power:

According to Sputnik, Russia's Deputy Permanent Representative to the United Nations Yevgeniy Zagaynov said about Churkin that he kept working "till the very end." The representative of the UN Secretary-General said that the UN was shocked by the news, extending their condolences to Moscow.
Perhaps the best known Russian diplomat alongside Sergey Lavrov, Vitaly Ivanovich Churkin was born in Moscow in 1952. He graduated from the Moscow State Institute of International Relations in 1974, beginning his decades-long career at the Ministry of Foreign Affairs shortly.
Ambassador Churkin, who held a Ph.D in history, served as Russia's Permanent Representative to the United Nations since 2006, where he has clashed on numerous occasions with opposing members of the Security Council whose decisions Russia has vetoed more than once. Prior to this appointment, he was Ambassador at Large at the Ministry of Foreign Affairs of the Russian Federation (2003-2006), Ambassador to Canada (1998-2003), Ambassador to Belgium and Liaison Ambassador to NATO and WEU (1994-1998), Deputy Foreign Minister and Special Representative of the President of the Russian Federation to the talks on Former Yugoslavia (1992-1994), Director of the Information Department of the Ministry of Foreign Affairs of the USSR/Russian Federation (1990-1992).
Churkin is survived by his wife and two children.
