Xi Jinping calls for closer ties with oil-rich Venezuela
Xi also wants more cooperation on global issues to help strengthen voice of developing nations
President Xi Jinping and his Venezuelan counterpart Nicolas Maduro have agreed to upgrade ties between their two countries.
Xi was in the Venezuelan capital Caracas on the third leg of his Latin American tour.
Venezuela has the world's largest proven reserves of oil, according to the international energy company BP.
During the nearly 15 years that late president Hugo Chavez was in power, China became a strategic ally of Venezuela in America's backyard.
China is the second-largest buyer of Venezuelan oil, with an average daily volume of 640,000 barrels, in part to pay off Venezuela's debt of some US$17 billion. Both countries aim to increase exports in the coming years to one million barrels a day.
