Law enforcement official: Churkin died after suffering from cardiac arrest in New York

Former US ambassador: Churkin was "a formidable adversary, but always a friend"

CNN  — 

Tributes poured in for Vitaly Churkin, the Russian ambassador to the United Nations who died suddenly Monday in New York.

Churkin died one day before his 65th birthday. He was known as a deeply intelligent, combative, disarming and humorous fixture at the UN Security Council.

The diplomat suffered from cardiac arrest while at the Russian Mission on East 67th Street, a law enforcement official said. He was taken to New York-Presbyterian Hospital, where he died.

Preliminary information suggests there was no foul play in Churkin’s death, New York police Lt. Thomas Antonetti said. But authorities are waiting for reports from the New York City medical examiner’s office before releasing the official cause of death.

The Russian Foreign Ministry said “the outstanding Russian diplomat died while he was in his current working role.” And President Vladimir Putin “expressed sympathy to the friends and family as well as to the staff of the Russian Foreign Ministry,” the Kremlin said.

What Vitaly Churkin’s death means for the United Nations

On Monday, members of the UN General Assembly stood for a moment of silence in memory of their colleague.

UN General Assembly President, Peter Thomson, said Churkin will be remembered for “his great intellect and his consummate diplomatic skills, and for his good humor and consideration for others.”

Thomson said Churkin will be remembered for “his great intellect and his consummate diplomatic skills, and for his good humor and consideration for others.”

Thomson added: “Not only has Russia lost one of its truest sons, but here at the United Nations, we’ve lost one of our truest.”

At the end of the moment of silence, Thomson said: “Rest in peace, dear Vitaly.”

A gracious, formidable colleague

“Ambassador Churkin was a uniquely skilled diplomat, a powerful orator with great wit, and a man of many talents and interests,” UN Secretary-General Antonio Guterres said.

Members of the Security Council said they were “deeply saddened” to learn of Churkin’s death. Churkin spent more than 40 years at the Russian Diplomatic Service and headed the Russian Mission to the United Nations for more than a decade, the Security Council said.

Churkin was often at odds with the United States, the United Kingdom and France. China would often take its cue from how Russia would vote.

For a decade, it was Churkin who raised his arm to veto numerous resolutions ranging from the Syrian crisis to the Malaysia Airlines crash over eastern Ukraine.

He stood firm in supporting Syrian President Bashar al-Assad’s regime against Western attacks. And he cited US policy in Libya as a symbol of failure by Western countries who favored regime change.

Nikki Haley, US ambassador to the United Nations, called Churkin “a gracious colleague.”

“We did not always see things the same way, but he unquestionably advocated his country’s positions with great skill,” she said in a statement.

Susan Rice, a former US envoy to the United Nations, said Churkin was “a formidable adversary, but always a friend.”

Another former US Ambassador, Samantha Power, said she was heartbroken by Churkin’s death and credited him with trying to help improve Russian-US relations.

“Devastated by passing of UN ambassador Vitaly Churkin,” Power tweeted. “Diplomatic maestro & deeply caring man who did all he (could) to bridge US-RUS differences.”

And Gérard Araud, a former French ambassador to the United Nations, said Churkin was an “extraordinary colleague” during Araud’s five years on the Security Council.

“Abrasive, funny and technically impeccable,” Araud tweeted about Churkin. “Sincere condolences.”
