BEIJING — The Asian Infrastructure Investment Bank (AIIB) announced Tuesday that it had approved a $335 million loan for an electric metro project in Bangalore, India.

The investment in the Bangalore Metro Rail Project-Reach 6 (R6) is the AIIB's first metro project and its first joint financing partnership with the European Investment Bank, which is the project's lead financier with 500 million euros (about $589 million) in funding," the AIIB said.

"We're investing in this metro project because of its potential to greatly improve the mobility of commuters and further economic growth through better connectivity," said AIIB Vice President and Chief Investment Officer D.J. Pandian.

The metro project is 100 percent electric.

"The project's impact on the reduction of fuel consumption and traffic congestion will also help reduce local air pollution and noise and make Bangalore a more livable city," Pandian was cited as saying in an AIIB press release.

By expanding the city's metro system, the project will provide high-capacity north-south connectivity through the center of Bangalore, India's third most populated city, with a population of 9.6 million, the bank said.

"Travel times for some journeys impacted by the lack of a metro system are expected to drop from two hours today to 15 minutes when the R6 line is completed," the AIIB said .

The announcement came a day after the AIIB said it had approved a $250-million loan for a natural gas project in China, the bank's first loan to a Chinese project.

Headquartered in Beijing, the China-proposed AIIB is a multilateral development bank focused on infrastructure investment, with a mission to improve social and economic outcomes in Asia and beyond.

The bank, which started operation in January 2016, currently has 80 approved members from around the world.
