China on 30 September 2016 blocked a tributary of the Brahmaputra River in Tibet. According to Chinese state run Xinhua news agency, China is constructing a hydro project on Xiabuqu River, a tributary of Brahmaputra in Xigaze in Tibet, closely located to Sikkim.
The blockade of the Brahmaputra river tributary may impact water flows into the lower riparian countries like India and Bangladesh.
This blockade of the tributary comes at a time when India has decided to suspend talks with Pakistan under Indus Water Treaty as part of its efforts to hit back at Pakistan in the aftermath of the Uri attack. Like the Brahmaputra, the Indus also originates in the Tibetan plateau in China.
