India, the US and several other world powers have been talking about the need to ensure a free, open and thriving Indo-Pacific in the backdrop of China's rising military manoeuvring in the region.

China claims nearly all of the disputed South China Sea, though Taiwan, the Philippines, Brunei, Malaysia and Vietnam all claim parts of it. Beijing has built artificial islands and military installations in the South China Sea.

During the delegation-level talks, Singh highlighted that the growing complexities in the India-Japan bilateral defence exercises is a testimony to the deepening of defence cooperation between the two countries, the Indian defence ministry said.

Further, with respect to defence equipment and technology cooperation, the ministers reaffirmed that the two countries would continue to work together towards concrete cooperation, it said.

They also welcomed increasing multilateral defence cooperation and exchanges including both Japan and India, including multilateral exercise Malabar involving Japan, the US, India and Australia being conducted for two years in a row.

The ministers reaffirmed that they would jointly promote multilateral initiatives which will contribute to upholding and reinforcing Free and Open Indo-Pacific.

They also exchanged views on the regional situation including the situation in Ukraine and highlighted their commitment to working in tandem towards a peaceful, stable and prosperous world, based on a rule-based order that respects sovereignty and territorial integrity of nations, the Japanese statement said.

They emphasised the need for all countries to seek peaceful resolution of disputes in accordance with international law without resorting to threat or use of force or any attempt to unilaterally change the status quo, it added.
