The Japanese requested President Roosevelt to initiate peace talks. Roosevelt convinced the Russian Tsar Nicholas that peace would be of benefit for both sides. Sergei Witte of Russia and Jutaro Komura of Japan negotiated the terms of peace in Portsmouth, New Hampshire, assisted by Roosevelt's third secretary of state Herbert Pierce.
