China has lodged seriously representations to Indonesia on Taiwan leader Chen Shui-bian's stopover in the islands nation, Foreign Ministry spokesman Liu Jianchao said on Friday.

Chen made a one-night stopover on the island of Batam in Indonesia on his way back from a trip to Latin America.

Liu said, "We demand Indonesia take practical action to fulfil its commitment to the one-China policy in order to maintain the overall Sino-Indonesian relations."

The Indonesian government voiced its serious regret over the activities carried out by Chen Shui-bian. Indonesian Foreign Ministry Spokesman Yuri Thamrin explained, "We had expected Chen's plane to arrive on the island at 2 p.m. Thursday for refueling and to leave straight away. But he stayed on the island until 10 a.m. on Friday and conducted some other activities."

"We still adhere to our one-China policy, and we hope our relationship with China will remain strong," he said.

Indonesian President Susilo Bambang Yudhoyono asked the governor of Kepulauan Riau province to submit a report about Chen's activities on the island and warned him to pay serious attention to the matter, according to Indonesian Chief Security Minister Widodo Adi Sucipto.
