BEIJING: China said it had summoned Japan`s ambassador a fifth time to demand Tokyo release a Chinese fishing boat captain arrested after a collision between his and two Japanese vessels in disputed waters.

Vice Foreign Minister Liu Zhenmin called in ambassador Uichiro Niwa on Tuesday to complain again over Japan`s continued "illegal detention" of the skipper, said a statement posted on the ministry`s website.

Liu "demanded that Japan immediately release and send back the Chinese boat captain."
