China which has already established a road and rail network in Nepal through Tibet, is now looking to stretch its railway link to Bihar to improve connectivity with India and South Asia.

A cross-border railroad link to the Rasuwagadhi area in Nepal has already been discussed between the two countries. China's railroad is expected to reach Nepal border by 2020, an article in the state-run Global Times said.

This rail line makes it possible to connect China to India as from Rasuwagadhi to Birgunj, which borders Bihar is only 240 km, the article said. For Bihar, trade with China through the rail link will be easier along this route than through Kolkata, saving time, cost and distance, it said.
