The end of the Indonesia-Singapore trade during the confrontation had made the economic conditions of the Riau Islands and Singaporeans disturbed. The inhabitants of Riau Islands can no longer barter or sell their produce to Singapore so that they cannot get basic necessities such as rice. Usually the basic needs of the Riau Islands population are brought in more from Singapore than anywhere else in Indonesia. Even vice versa, the supply of some needs of Singapore residents who are usually imported from the Riau Islands has been disrupted. Hostilities ceased in 1966 after the 30 September Movement attempted a coup d'état, resulting in the overthrow of the Sukarno regime which leads to a peace agreement between Indonesia and Malaysia that was signed on 28 May 1966 at Bangkok, Thailand.
