The French envoy asserted the negotiations for the $20 billion MMRCA (medium multi-role combat aircraft) project for 126 Rafale fighters were on fast track and expected them to be finalised soon. "The feasibility study is going on in the Mumbai-Ahmedabad high speed rail project. We are good at bullet trains and recently I had a talk with Railways Minister Suresh Prabhu where we discussed about how we can extend our cooperation in railways including in the fields of technology and other expertise," Richier, on a three-day visit to the city, told mediapersons.
