Question: How many Korean diaspora are there in the Philippines? Passage:Koreans in Vietnam is a community of Vietnam with a population of Korean expatriates along with Vietnamese citizens of Korean ancestry. The population initially came in a military capacity, fighting on both sides of the Vietnam War. After the end of the war, there was little Korean migration or tourism in Vietnam, until the rise of the South Korean economy and the decline of the North resulted in an influx of South Korean investors and North Korean defectors, as well as South Korean men seeking Vietnamese wives. As of 2011, according to statistics of South Korea's Ministry of Foreign Affairs and Trade, they numbered roughly eighty thousand people, making them the second-largest Korean diaspora community in Southeast Asia, after the Korean community in the Philippines, and the tenth-largest in the world. A more recent estimate from Vietnam Television says their population might be as large as 130,000.
