Diplomatic efforts between the Netherlands and the Republic continued throughout 1948 and 1949. Political pressures, both domestic and international, hindered Dutch attempts to decide upon objectives. Similarly, Republican leaders faced great difficulty in persuading their people to accept diplomatic concessions. By July 1948 negotiations were in deadlock and the Netherlands pushed unilaterally towards Van Mook's federal Indonesia concept. The new federal states of South Sumatra and East Java were created, although neither had a viable support base. The Netherlands set up the "Bijeenkomst voor Federaal Overleg (BFO)" (or Federal Consultative Assembly), a body comprising the leadership of the federal states, and charged with the formation of a United States of Indonesia and an interim government by the end of 1948. The Dutch plans, however, had no place for the Republic unless it accepted a minor role already defined for it. Later plans included Java and Sumatra but dropped all mention of the Republic. The main sticking point in the negotiations was the balance of power between the Netherlands High Representative and the Republican forces.
