The Communist Party of Burma (Burmese: မာပြည်ကွန်မြူနစ်ပါတီ; CPB) is the oldest existing political party in Burma. The party is unrecognised by the Burmese authorities, rendering it illegal; so it operates in a clandestine manner, often associating with insurgent armies along the border of People's Republic of China. It is often referred to as the Burma Communist Party (BCP) by both the Burmese government and the foreign media.
