(Yicai Global) Jan. 16 -- Russia's largest gold mining concern, Polyus Gold International Ltd., has called off an agreement to sell 12,519,000 of its shares to Chinese investment conglomerate Fosun International Ltd. citing an undisclosed unmet condition, Fosun International said in a press briefing yesterday.

The Shanghai-based firm did not confirm the percentage stake of the share amount, though Russia's Sputnik News had reported earlier that it made up 15 percent of the company's equity.

Fosun International will look for other investment opportunities in Russia, it added.
