Some party members were outside Indonesia at the time of the 30 September events; a sizeable delegation had traveled to the People's Republic of China to participate in the anniversary celebration of the Chinese Revolution. Others had left Indonesia to study in Eastern Europe, particularly Albania. Although the party apparatus continued to function in exile, it was largely isolated from political developments in Indonesia. In Java, some villages which were known refuges for members (or suspected sympathizers) were identified by authorities and closely watched for a long time.
