Malaysia protests presence of Chinese vessels in its waters

The protest was over the "presence and activities" of Chinese vessels, including a survey vessel, in Malaysia's Exclusive Economic Zone off the coasts of the eastern states of Sabah and Sarawak, the ministry said in a statement on Monday.

It did not say when the vessels were detected in Malaysian waters.

"Malaysia's consistent position and actions are based on international law, in defence of our sovereignty and sovereign rights in our waters," the foreign ministry said.

The Chinese embassy in Kuala Lumpur did not immediately respond to a request for comment.

Last week, media reported that a Chinese survey vessel was in Malaysian waters off the coast of Sabah, near a vessel commissioned by Malaysian state energy firm Petronas.

Last year, another Chinese survey ship held a month-long standoff with an oil exploration vessel contracted by Petronas within Malaysia's exclusive economic zone. China had then said the vessel was conducting normal activities.

Malaysia's foreign ministry also said that all matters related to the South China Sea must be resolved peacefully and constructively.

"In determining Malaysia's position and course of action with regard to the South China Sea issue, which is complex and involves inter-State relations, Malaysia's national interests will remain of paramount importance," it said.

China claims almost all of the energy-rich South China Sea, through which about $3 trillion worth of ship-borne trade passes annually.

Malaysia, Brunei, the Philippines, Taiwan and Vietnam have overlapping claims.
