Kamynin made his comments on the eve of a visit by German Chancellor Angela Merkel to Moscow on March 8 for talks with outgoing Russian President Vladimir Putin and his successor Dmitry Medvedev. Merkel will be arriving in Moscow on International Women's Day, celebrated as a national holiday in Russia and several ex-Soviet countries.
Kamynin said bilateral cooperation was based on economic relations.
"The most important task today is to increase the number of joint projects, first of all, in the sphere of high technology, including energy, aviation, outer space, car-making, transport, telecommunications and communications," Kamynin said.
The Russian diplomat said the Nord Stream pipeline, which Russian energy giant Gazprom is building together with Germany's E.ON under the Baltic Sea to pump Russian natural gas to Germany, was a priority project in bilateral cooperation.
