China is planning to extend its railway line to Tibet to reach India, Nepal and Bhutan. The accompanying infographic shows a map of the plans as well as the costs of the portions that have been completed.

According to Reuters, critics believe the railway has threatened the cultural integrity of Tibet, spurring an influx of long-term migrants. They argue that extending the railway further would drastically exacerbate the problem.

The New York Times adds that there is contention between China and India over some borders in the Himalayan region. The railway plans have alarmed India, which is working to fortify its posts in those areas.
