Germany and Russia have sealed an accord on moving Lufthansa Cargo's regional transit hub from Astana in Kazakhstan to Krasnoyarsk in Siberia, the transport ministry in Berlin said on Friday.

After two days of talks in Munich, the two sides agreed Lufthansa Cargo's aircraft would begin landing at Krasnoyarsk at the latest five months after modernization work at the airport there had been completed, the ministry said.

Over-flight rights for the cargo aircraft would be extended until the end of the summer flight timetable on August 30, and Lufthansa would also be granted new over-flight rights to South Korea, it added.

Russia stopped Lufthansa cargo planes from flying through its airspace at the end of October, saying the German carrier should move its regional hub to Siberia as agreed.

Lufthansa Cargo uses Astana, its second-biggest cargo airport after Frankfurt, as a connecting point for flights to southeast Asia.

A spokesman for Lufthansa said on Friday that the over-flight rights and the hub switch were not tied together.

"When the operational and commercial conditions are met and a lead time of five months is guaranteed, we will move to Krasnoyarsk," the spokesman said.

German and Russian officials were scheduled to meet again in Krasnoyarsk in September to discuss progress in the building work at the airport, the German transport ministry said.
