Calling for "intensification in inter-regional exchanges," Xi and Mirziyoyev stressed the need to continue joint efforts to promote the peace process in Afghanistan and the war-ravaged country's economic recovery, Uzbek news website Kun.uz reported.

They also called for "systemic interaction within the framework of international and regional structures, including the Central Asia-China mechanism," the report added.

According to China's Foreign Ministry, Xi said the two sides need to "expand energy cooperation, jointly ensure the safe operation of the China-Central Asia natural gas pipeline and extend cooperation to new energy, with a view to fostering a new pattern of all-dimensional energy cooperation."

"China and Central Asian countries have a shared future and a deep stake in each other's security and stability," he added.

"China is ready to work more closely with Uzbekistan to firmly oppose external interference in internal affairs, firmly safeguard domestic stability and firmly defend the security interests of the region," he said.
