North Korea's premier Kim Yong Il arrived in Vietnam on Friday for a five-day visit aimed at boosting ties between the two communist countries, DPA quoted news reports as saying. The visit by Kim Yong Il - who is not related to North Korean leader Kim Jong Il - is part of a South-East Asian tour by the premier of the isolated state. Kim Yong Il arrived in Vietnam to seek cooperation in farming and mining technology, an unidentified diplomatic source was quoted as saying in Hanoi by the South Korean Yonhap news agency. Kim, also responsible for economic policy, is visiting Hanoi following last week's trip by Vietnam's Communist Party leader Nong Duc Manh to Pyongyang where he met with Kim Jong Il and extended an invitation for the supreme leader to visit Vietnam later this year.
