China's Civil Aviation Administration of China (CAAC) has vowed to strengthen international connectivity and global reach of its major airports, aiming to build world-class aviation enterprises and air hubs by 2050. 

CAAC will boost intercontinental connectivity and global influence of the airports in Beijing, Shanghai and Guangzhou, upgrading them into world-class aviation hubs, Han Jun, deputy administrator of CAAC, said on Wednesday. 

It is part of the administration's latest efforts to enhance transit efficiency, and streamline entry and exit process.

The CAAC will focus on elevating the capacities of major hubs in China, building international and regional hub airports in cities across China, and advancing development of air cargo hubs such as the Ezhou Huahu Airport in Ezhou, central China's Hubei Province.

The administration also plans to optimize resource allocation for airlines. CAAC also stressed the importance of improving operation efficiency of Chinese airports, airlines, and air traffic control, and aim to boost the overall transport capacity of aviation hubs with integrated transportation system.

Efforts will also be made to create a more convenient policy environment, by optimizing visa and immigration policies, as well as easing customs clearance.
