The resilience of Indonesian Republican resistance and active international diplomacy set world opinion against the Dutch. The United States pushed the Netherlands government into negotiations. The Dutch–Indonesian Round Table Conference was held in The Hague from 23 August 1949 to 2 November 1949 between the Republic, the Netherlands, and the Dutch-created federal states. The Netherlands agreed to recognise Indonesian sovereignty over a new federal state known as the 'United States of Indonesia' (RUSI). It would include all the territory of the former Dutch East Indies with the exception of Netherlands New Guinea; which was retained by the Netherlands until further negotiations with Indonesia. Sovereignty was formally transferred on 27 December 1949.
