The Netherlands relinquished its territorial claims in the archipelago (with the exception of West Papua) following the 1949 Round Table Conference. In the same year that the Kuomintang retreated to Taiwan, allowing the Communist Party of China to take control of mainland China. Most Chinese Indonesians considered a communist China less attractive than a newly independent Indonesia, but in the archipelago their loyalties were questioned. Ethnic Chinese born in the Dutch East Indies whose parents were domiciled under Dutch administration were regarded as citizens of the new state according to the principle of "jus soli", or "right of the soil". However, Chinese law considered a person as a Chinese citizen according to the principle of "jus sanguinis", or right of blood. This meant that all Indonesian citizens of Chinese descent were also claimed as citizens by the People's Republic of China. After several attempts by both governments to resolve this issue, Indonesia and China signed a Dual Nationality Treaty on the sidelines of the 1955 Asian–African Conference in Bandung. One of its provisions permitted Indonesians to renounce Chinese citizenship if they wished to hold Indonesian citizenship only.
