Chairperson of Parliamentary Standing Committee on Science and Technology, Environment and Forests Renuka Chowdhury said though the issue of China building a dam on Brahmaputra river was hypothetical, India would have answers if China takes such a step.
"If and when they (China) build a dam on the Brahmaputra, India will have the answers," Chowdhury told reporters.
"At this point the situation is hypothetical and it is a sensitive issue. It is something which the Government of India has to take a call on if and when such thing happens," the Congress MP said.
"Since it hasn't happened yet, we must exercise great caution to see that we don't promote rumour mongering," she said.
Chowdhury who came here leading a 11-member team reviewed activities of the North Eastern Space Applications Centre (NESAC) here.
