Russia and India signed a clutch of defence and energy deals on Thursday as prime minister Narendra Modi visited Moscow to reaffirm one of the world's most valuable military relationships.
Following a meeting with Russian president Vladimir Putin, the two leaders announced deals to build Russian-designed Kamov helicopters in India and for the location of a new nuclear power plant to be built by Russian state nuclear company Rosatom.
India, the world's largest importer of defence equipment, is set to spend $250bn over the next decade modernising its antiquated hardware. But Mr Modi has made it a key policy to push for these new weapons systems and other equipment to be made mostly in India rather than abroad.
Mr Modi hailed the deal for the production of helicopters as the first major defence project under his "Make in India" programme. Under the deal with Rosatom, some equipment for nuclear power plants would also be built in India.
Russia and India have long been one another's top defence partners, a relationship dating back to Soviet times. But in recent years, India has sought to broaden its diplomatic relations and has also been ordering military hardware from a more eclectic array of supplier, including the US.
But Mr Modi has also indicated that he still sees Russia as one of India's most reliable friends, and has made clear that he wishes to revive and deepen the frayed strategic ties, especially in areas such as nuclear power and defence.
