"All of the five airports have ample room for further development as we transform PRD into a more competitive, world-class city cluster. We hope that the airports can continue to work together to seize the opportunities ahead, deepen their cooperation and leverage on each others' strengths to build a strategic cooperation platform. This will help boost the aviation economy of the country, driving the prosperity of the international and domestic aviation market and increasing the pace of change for PRD's industry structure and economic development to make great contributions to the region," Xia Xinghua, the vice minister of Civil Aviation Administration of China, said in a statement. The administration, as well as the Transport and Housing Bureau of the HKSAR, joined in the meeting.

The gathered representatives talked about strengthening communication among the airports and discussed development, multi-modal transportation and the possibility of opening low-altitude airspace in the region. Airlines that signed the MoU agreed to help improve their respective infrastructures for the good of the group and to regularly exchange air traffic flow data.

"With the PRD economy growing even stronger, demand for air passenger and cargo traffic continues to surge. In the long term, even if the five airports deliver on all of their planned expansions, we still will not be able to meet the rising demand for aviation services," Dr. Marvin Cheung Kin-tung, chairman of the Airport Authority Hong Kong, said in a statement. "It will be in the best interests of the five airports to foster closer cooperation and complement each other to boost economic development in the region while stepping up their efforts to meet the demand for future growth."
