US Vice President Joe Biden lauded land-locked Mongolia's efforts at democratization on Monday, offering support to a country that is strategically located between China and Russia and sits on vast quantities of untapped mineral wealth. Biden, arriving from China for a day-long trip before going on to Tokyo, praised Mongolia for its uptake of democracy following decades of domination by the Soviet Union. “We've grown much closer since the Mongolian people began to embrace ... democracy 22 years ago,” he said after meeting Prime Minister Sukhbaatar Batbold in capital Ulan Bator. “The United States remains strongly committed to helping the Mongolian people build a better future,” he said, adding that visits by him and his boss, President Barack Obama, this year showed how impressed Washington was with Mongolia's progress. Mongolia, perhaps best known for the warrior-emperor Genghis Khan, was ruled as a one-party satellite of the Soviet Union for much of the last century. After seven decades of communist rule, Mongolia held its first free multi-party elections in 1990. But its transition to democracy has had rocky patches. In 2008, a disputed election led to rioting on the streets of Ulan Bator, in which at least five people died. In 2005, George W. Bush became the first U.S. president to visit the country and thanked Mongolia for supporting the Iraq war and hailed its progress to democracy. Mongolia sent some 120 soldiers to support U.S. troops in Baghdad in 2003, and it has also sent peacekeepers to other parts of the world. “Americans admire and appreciate Mongolia's contribution to international peace and security,” Biden said. Jargalsaikhan Dambadarjaa, a Mongolian economist and political commentator, said his country felt more political kinship with the United States than either of its neighbours, China or Russia. “The relationship with the United States is very important for this country because we are in the middle of these two giants,” he said. A small group of demonstrators, however, took to the streets earlier to protest what they said were U.S. plans to store nuclear waste in the country, something the Mongolian government has denied. Ulan Bator has been keen to cultivate new relationships with what it calls “third neighbours” like the United States, though China dominates Mongolia's economy, buying 90 percent of the country's exports in the first half of 2011.
