"A proposed extension of the Qinghai-Tibet Railway to the China-Nepal border through Tibet would boost bilateral trade and tourism as there is currently no rail line linking the two countries," state-run China Daily reported today.
The rail line was expected to be completed by 2020. However, there was no word on the cost of the project.
The 1,956-km long Qinghai-Tibet railway already links the rest of China with the Tibetan capital Lhasa and beyond. Wang Mengshu, a rail expert at the Chinese Academy of Engineering, said that engineers will face a number of difficulties once the project begins.
"If the proposal becomes reality, bilateral trade, especially in agricultural products, will get a strong boost, along with tourism and people-to-people exchanges," he said.
Such a plan could see a tunnel being built under Mount Everest, the China Daily said.
"The changes in the elevation along the line are remarkable. The line is probably have to go through Qomolangma so that worker may have to dig some very long tunnels," Wang said. Qomolangma Mountain is the Tibetan name for Mt Everest.
Restrained by rugged Himalayan mountains with its "remarkable" changes in elevation, trains on the line would probably have a maximum speed of 120 kmph.
Wang said that the project is being undertaken at Nepal's request and that China has begun preparatory work.
Losang Jamcan, Chairman of the Tibet Autonomous Region, told Nepalese President Ram Baran Yadav during his visit to Tibet's provincial capital Lhasa last month that China plans to extend the Tibet railway to Kermug, the Chinese town nearest to Nepal border where a border trade port has been built.
Besides Nepal, China had earlier announced plans to extend its Tibetan rail network to Bhutan and India.
During his recent visit to Nepal, Chinese Foreign Minister Wang Yi had asked the officials to conduct a feasibility study to extend the rail network to Kathmandu and beyond, the report said.
Hu Shisheng, Director of the China Institute of Contemporary International Relations, told official media earlier that the aim of the rail line is to simply improve the local economies and people's livelihoods.
China, has been scaling up its ties with Nepal, much to the chagrin of India to stem the flow of Tibetans travelling through Nepal to meet the Dalai Lama in Dharamshala.
Beijing recently increased its annual aid to Nepal to USD 128 million from the previous USD 24 million.
