Russia is considering giving priority to a new route for the Siberian oil pipeline that would be favorable to Japan, informed sources said Sunday.

Japan and China have submitted proposals for two competing routes for the pipeline. If the new route, drawn up by a Russian state-run corporation, is adopted, it would be a big step forward toward realization of the $10 billion project.

The Russian administration is more inclined toward the Japanese route in the hope of winning large investments from Japan as well as the expansion of the Asian market, the sources said.

Meanwhile, China is increasing pressure on Russia through its weapons industry, with which China has close ties, according to the sources.
