Activists on a Hong Kong ship seeking to assert China's claim to a group of Japanese-controlled islands in the East China Sea were expected to reach Taiwan late Monday, and the islands two days later.

The activists, who hail from Hong Kong, Macao and Shenzhen, were cruising northward off Shanwei in Guangdong Province at noon Monday, Hong Kong's Phoenix TV reported.

The vessel is expected to reach the disputed islands on Wednesday, barring interference, said Chan Miu-tak, chairman of the activist group Action Committee for Defending the Diaoyu Islands.
