For the International Liaison Department of China, see International Department of the Communist Party of China.
The OMS (Russian: Отдел международной связи, otdel mezhdunarodnoy svyazi or ОМС), also known in English as the International Liaison Department (1921–1939[1][2]), was "the most secret department" of the Executive Committee of the Communist International. It has also been translated as the Illegal Liaison Section[3][4] and Foreign Liaison Department.[5]
