BEIJING (PTI): China said on Tuesday that military cooperation between countries should be conducive to regional peace, a day after Quad members, including India, joined France in a mega naval wargame in the Indian Ocean amid Beijing's aggressive actions in the region.

India and three other Quad member nations – the US, Australia and Japan – on Monday joined France in kick-starting the three-day naval exercises in the eastern Indian Ocean in reflection of their growing maritime cooperation amid China's increasing efforts to expand influence in the region.

The Indian Ocean, considered the backyard of the Indian Navy, is critical for India's strategic interests. China has been making concerted efforts to increase its presence in the region.

Asked for his reaction to Quad alliance countries joining the French naval exercises 'La Perouse' amidst reports that the drills are aimed to contain and check China, Chinese Foreign Ministry spokesman Zhao Lijian on Tuesday reiterated Beijing's stand that such a cooperation should be conducive to peace in the region.

"I noted these reports. We always believe that military cooperation between countries should be conducive to regional peace and stability," he told a media briefing in Beijing.

During the drills, the Indian Navy ships and aircraft will exercise at sea with ships and aircraft of navies of France, Australia, Japan and the United States. Indian naval ships Satpura and Kiltan along with P-8I long range maritime patrol aircraft are participating in multilateral exercises.

India has been expanding cooperation with navies of the US, Japan, Australia and France in the last few years.

Indian Navy Spokesperson Commander Vivek Madhwal said the exercise will witness complex and advanced naval operations including surface warfare, anti-air warfare and air defence exercises.

"The exercise will showcase high levels of synergy, coordination and interoperability between the friendly navies," he said.

"Participation by Indian Navy in the exercise demonstrates the shared values with friendly navies ensuring freedom of seas and commitment to an open, inclusive Indo-Pacific and a rules-based international order," Madhwal said.

China claims sovereignty over all of South China Sea. Vietnam, Malaysia, the Philippines, Brunei and Taiwan have counter claims.

China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. Beijing has built up and militarised many of the islands and reefs it controls in the region. Both areas are stated to be rich in minerals, oil and other natural resources and are also vital to global trade.
