Russia and China will launch joint heavy drilling rigs in a deal between two corporations, the report said.
On another issue, the agriculture ministries of the two countries will work together in the breeding of rabbits, with Russian and Chinese companies signing a cooperation agreement, RIA Novosti said.
The deals were signed as new Chinese President Xi Jinping made his way to Russia for a three-day visit, the BBC said. He arrived Friday.

"China-Russia relations have entered a new phase in which the two countries provide major development opportunities to each other," he said.
