India and Russia are expected to sign this weekend a “complex agreement” for production of 200 Kamov 226T helicopters domestically under a nearly $1 billion deal to replace the country’s ageing Cheetah and Chetak choppers.

The agreement is expected to be inked on the sidelines of the 2016 BRICS Summit in Goa from October 13 to October 16.

A variety of negotiations on the expansion of military-technical cooperation and fortification of trade relations with India will be held.

“The complex agreement to set up a joint production facility of Ka-226T helicopters is expected to be signed at the BRICS forum,” said a statement by Rostec State Corporation.
