AsianFin -- A U.S.-owned canned food company nationalized by Russia to secure domestic food supplies is now seeking to revive declining sales through exports to China and North Korea, according to documents reviewed by Reuters and people familiar with the matter.

The company, Glavprodukt, remains the only American business Moscow has formally seized. Washington has warned that how Russia handles the case will factor heavily into any potential reset of U.S.-Russia relations, which have shown little progress in recent months.
