Amid reports that it was building a dam in Tibet on Brahmaputra river, China on Thursday assured India that it will not do anything to damage other nations' interests.

"China is a responsible country and will not do anything to damage the interests of others," Foreign Ministry spokesman Ma Zhaoxu said in a bi-weekly press briefing when asked to comment on reports that China was building a dam on Yarlung Zangbu River or Brahmaputra.

Foreign Secretary Nirupama Rao had said on Wednesday that India had repeatedly raised with China the issue of construction of a dam by it on Brahmaputra river and Beijing had consistently denied any such engagement.

"What I want to say is that this matter has been taken up not just once but on a number of occasions with China, and China has consistently denied that it is engaged in any such construction activity on the Brahmaputra," Rao said in New Delhi.

She was replying to a question on the reported construction at the Zangmu site on the Chinese side of the Brahmaputra river, which was confirmed by the National Remote Sensing Agency (NRSA) as per media reports.

The issue had also figured in the meeting between Prime Minister Manmohan Singh and his Chinese counterpart Wen Jiabao on the sidelines of the ASEAN-India and East Asia Summit in Thailand last month.
