Russia, Venezuela Coordinate on Energy

MOSCOW — President Hugo Chávez of Venezuela and President Dmitri A. Medvedev of Russia declared Tuesday that their countries would more closely coordinate their actions on global oil and gas markets and that they would work together on foreign policy, a sphere in which both countries have sought to counter American influence. Mr. Chávez, who was also expected to sign contracts to purchase more than $1 billion worth of Russian arms, called for the two nations to become "strategic partners" to defend against what he called an American threat to his country.
