Russia has for the first time sent two trains laden with coal to India via the International North-South Transport Corridor (INSTC), which connects Russia to India via Iran, according to a statement by Russia’s national railway company.

According to RT, a multimodal route that includes a railway, roadway network and seaports, the INSTC spans 7,200km (4,500 miles) from St. Petersburg to the port of Mumbai in India.

The corridor is part of Russia’s push to find new transport routes in light of Western sanctions, which have forced it to shift trade flows from Europe to Asia and the Middle East.

Construction of the INSTC started in the early 2000s, but developing it further has taken on a new impetus in light of the restrictions facing Moscow.

New Delhi has also touted the route as an alternative to China’s Belt and Road Initiative.

“For the first time, two trains with Kuzbass coal headed to India along the International North-South Transport Corridor. The trains set off from the Kemerovo region. They followed along the eastern branch of the INSTC through Kazakhstan and Turkmenistan to the Iranian port of Bandar Abbas,” Russian Railways said on Monday in its Telegram channel.

The coal will be shipped by sea along the final part of the route from Iran’s port of Bandar Abbas to the Indian port of Mumbai, according to the statement.
