"There is a clause in the Indo-Nepal Treaty of Trade and Transit, 1991, which only allows present movement by road and rail from India to Nepal. This clause is now being amended, which is at a very advanced stage. The Union Ministry of Commerce is taking the lead in the amendment," Inland Waterways authority of India Chairman Pravir Pandey said.
"Couple of meeting have already been held and they have drafted the amended clause. It will very soon see the light of the day."
According to Pandey, a technical scoping mission went to Nepal last year and a technical team from the neighbouring country also visited India.
"Thereafter in April, a high level delegation comprising officials from Customs and the Ministries of Commerce and External Affairs visited Nepal.
"Three water routes have been accepted by both the countries. There is in-principle approval of all these agencies of India and Nepal on the three routes," he said on the sidelines of the Inland Waterways Summit organised here by the Indian Chamber of Commerce.
The routes are the Kolkata-Sahebganj waterway and then to Nepal's Biratnagar by road, Kolkata-Kalughat near Patna by waterway and then to Birgunj and the Kolkata-Varanasi (waterway) and then to either Nepalganj or Mahendra Nagar, he said.
The Nepal government had also requested India to explore whether the Gandak river could be used as a waterway right up to the border of these two countries.
"We have responded that it needs technical studies whether the ships of larger size can move through Gandak upto Nepal," he added.
