Former US Secretary of State Henry Kissinger has died at the age of 100. Chinese Ambassador to the United States Xie Feng sent a message of condolences.

"I am deeply shocked and saddened to learn that Dr. Kissinger has passed away at the age of 100," Xie said on social media X. I send my deepest condolences to Nancy and her family. This is a great loss for both our countries and for the world. History will remember the centenarian's contribution to China-Us relations. He is the most precious old friend of the Chinese people and will always live in the hearts of the Chinese people."

Kissinger's death was announced in a statement by his consulting firm on November 29, local time.

Kissinger played an important role in establishing diplomatic relations between the United States and China. In 1971, Kissinger, then the US President's Assistant for National Security Affairs, secretly visited China and joined hands with the Chinese side to facilitate President Nixon's "ice-breaking trip" to China in 1972, and realized the "handshake across the Pacific Ocean" that shook the world.

Former US President George Bush has led tributes to former Secretary of State Henry Kissinger, who has died at his home.

Former US President George W. Bush said in a statement released through his foundation that the United States had "lost its most reliable and distinctive voice on foreign affairs."

"I have always admired Henry Kissinger, who fled the Nazis at a young age from a Jewish family and fought against them in the United States Army," the statement said.

"He has worked in two presidents' administrations and advised many more. I am grateful for his service and advice, but most of all I am grateful for his friendship."

Bush said he and his wife will miss Kissinger's wit, charm and humor.
