North Korean leader Kim Jong-il may visit key ally China next week amid heightened concern over a possible nuclear weapons test by the reclusive state and its defiant missile launch in July, a news report said on Thursday. Kim's visit will be primarily to discuss the North's possible nuclear test with Chinese President Hu Jintao, the daily Chosun Ilbo reported a diplomatic source in Seoul as saying. "Authorities in Seoul and Washington were briefed that Kim Jong-il is to take a three-day trip to China around August 30," the source told the newspaper. Officials at South Korea's foreign ministry could not immediately be reached for comment.
