MOSCOW, August 07. /ITAR-TASS/. Russia is working on measures to close its airspace to Western companies’ flights to and from the Asia-Pacific region and also to change the points of entry and exit for charter flights, Prime Minister Dmitry Medvedev said at a meeting of the Cabinet on Thursday.

“The current situation as it is, the Russian government is considering a number of retaliatory steps. I will mention some of them, but that does not mean that they will be introduced at once. The measures include a ban on transit flights by European and US air carriers to Southeast Asia, to the Asia-Pacific Region,” Medvedev said.

“We are considering measures that would be an answer to the European Union’s sanctions against the Russian air company Dobrolyot, which flied to Simferopol,” he said.

Russian has banned Ukrainian air companies to make transit flights to a number of countries via Russia, Russian Prime Minister Dmitry Medvedev said on Thursday.

He said the decision had already been taken.

Russia is working out measures to revise the rules of using Trans-Siberian routes, Prime Minister Dmitry Medvedev said.

“Our country is ready to revise the rules of using Trans-Siberian routes, that is, denounce the agreed principles of upgrading the existing system of Trans-Siberian routes,” he said at a government session.

The Russian Association of Air Transport Operators on Monday asked the government to take urgent measures to support the Dobrolet low-cost air carrier that has had to stop operation due to Western sanctions.

Russia's Dobrolyot, a low-cost airline, is 100-percent subsidiary of Russia’s biggest air carrier Aeroflot. Its fleet includes two Boeings 737-800 NG and one Sukhoi Superjet-100. By the end of 2014, the company planned to add six more Boeings to its fleet. Both of its Boeings are leased from BBAM Aircraft Leasing and Management.

 The Russian government is ready to introduce protective measures in the aircraft building, shipbuilding and automobile manufacturing industries, Prime Minister Dmitry Medvedev said at a Cabinet meeting on Thursday.

“We are potentially ready to introduce protective measures in aircraft building, shipbuilding, automobile manufacturing industries and in other sectors, but we will do this sensibly,” he said.

The prime minister also said the government realised the importance of co-operation in this sphere and looked realistically on the country’s capabilities.
