Camaraderie as Mighty as the Yellow River and the Volga

Amid the lush greenery of Xishan Park in Wanzhou, Chongqing, stands the tomb of Grigori Kulishenko, captain of a Soviet Union air squadron.

During his 2013 visit to Russia, President Xi Jinping paid tribute to him in a speech at the Moscow State Institute of International Relations.

In 1939, Kulishenko led a group of Soviet pilots to support the Chinese People's War of Resistance Against Japanese Aggression.

His aircraft was badly damaged in combat, forcing him to make an emergency landing on the Yangtze River near Wanzhou, where he was swept away by the current.

A cemetery was built in his honor in 1958.

A local family has tended it for more than six decades, a testament to the friendship between China and Russia.
