Dwarkanath Shantaram Kotnis, 10 October 1910 in India – 9 December 1942 in China), also known by his Chinese name Ke Dihua was one of the five Indian physicians dispatched to China to provide medical assistance during the Second Sino-Japanese War in 1938. Known for his dedication and perseverance, he has been regarded as an example for Sino-Indian friendship and collaboration.

The team first arrived in China at the port of Hankou, Wuhan. They were then sent to Yan'an, the revolutionary base at the time in 1939, where they were warmly welcomed by Mao Zedong, Zhu De and other top leaders of the Communist Party, as they were the first medical team to come from another Asian country.
