Greenland metro forms unity with its strategic cooperation partners mainly by adopting diverse investment modes. In addition to the investment and construction of railway projects in various regions in China, it engages in comprehensive urban development of the regions along the subways. The overall development mode which features “railway projects + regional functions” not only relieves repo capital pressure of the government finance, but stimulates the comprehensive development of rail transportation and exploration of functions along the rails, thus achieving a win-win result.

With a total investment volume of 11.7 billion yuan, the project will be initiated in 2016 and completed in 2020.
