Bangladesh and China have finalised plans on the Teesta River water-sharing arrangement, clearing a significant diplomatic hurdle between the two neighbours. The agreement, which has been the subject of protracted negotiations, addresses longstanding concerns over equitable distribution of the transboundary river's waters during different seasons.

Simultaneously, the two countries have advanced discussions on Bangladesh's potential acquisition of Chinese military hardware. These preliminary talks have now progressed to the threshold of formal negotiations regarding the purchase of J-10CE fighter jets and attack helicopters, marking a substantial expansion of Bangladesh's defence cooperation with China.

The dual breakthrough reflects deepening ties between Dhaka and Beijing across diplomatic and strategic domains. For Bangladesh, the Teesta accord represents progress on a regional water-sharing issue that has repeatedly strained relations with neighbouring countries, while the military procurement discussions signal the country's modernisation of its defence capabilities.

The J-10CE, a multi-role combat aircraft developed by Chengdu Aircraft Corporation, represents a significant platform that would enhance Bangladesh's aerial defence capabilities. The inclusion of attack helicopters in discussions indicates Bangladesh's intent to develop a more comprehensive air arm suited to its strategic requirements in the region.
