Brewster Aeronautical Corporation's Buffalos were exported to the United Kingdom for the battles in the Far East but were inferior to the Japanese Zeros manufactured by Mitsubishi Aircraft Company.
The United Kingdom also received Buffalos, which eventually ended up in the Far East. They suffered badly in combat against Japanese Zeros. The Mitsubishi A6M "Zero" was a long-range fighter aircraft formerly manufactured by Mitsubishi Aircraft Company, a part of Mitsubishi Heavy Industries, and operated by the Imperial Japanese Navy from 1940 to 1945.
