Moscow has agreed to allow Japan to increase the number of code-sharing flights its airlines can operate in Siberian skies with non-Russian airlines, the transport ministry said Thursday.

During two days of Japanese-Russian aviation talks that ended Wednesday, Russia agreed to allow Japanese airlines to increase their flights over Siberia to a maximum of 23 a week, effective immediately, according to the Land, Infrastructure and Transport Ministry.

Previously, Japan Airlines and All Nippon Airways could operate up to 15 code-sharing flights per week with other international airlines.

Russia also agreed to allow code-sharing flights over Siberia that stop in Amsterdam to fly into Hungary and Poland, as well as to two locations in Spain.
