By late 1978, a new elite coalition had assumed power in Beijing, and was composed of policy-makers from the post-Great Leap Forward (GLF) period, including Deng Xiaoping and Chen Yun. Promoting a new approach to China's development, they expanded the role of the international economy in China. The new coalition augmented plan-oriented export promotion policies, and partially decentralized domestic and foreign economic controls for Guangdong and Fujian provinces. They also agreed to "actively" use foreign capital, and authorized the establishment of the Special Economic Zones (SEZs) on the southeastern coast. Although problems would arise during actual policy implementation that would contribute to the decay of the post-GLF elite coalition, a new elite coalition would form by 1984—without Chen Yun. Under Deng Xiaoping's leadership, this coalition would aggressively embrace an export-oriented development strategy incorporating all of China's coastal regions.
