The Treaty provided for Portuguese administration to officially end on 20 December, 1999. Although it would become a full part of the People's Republic of China, Macao would enjoy the status of a Special Administrative Region (SAR), with full autonomy and self-governance in domestic affairs, economic policy and internal security. The system of "One country, two systems" would be established, exempting Macao from the Socialist system and several laws decreed by the central government in Beijing. The capitalist, legal system and liberal society enjoyed by Macau would remain unchanged for a minimum of 50 years after the transfer. The Chinese government would not levy taxes on Macau nor make laws pertaining to Macau's governance. The Macau SAR would enjoy a great degree of autonomy in all but foreign affairs and defence, which would remain under Chinese control. Bearing the name of "Macao, China," Macao would enjoy the right to conclude agreements and arrangements with Portugal and international organisations for its own development.
