China's Foreign Ministry strongly opposes India's accelerated hydropower projects in Arunachal Pradesh, claiming the region as South Tibet and asserting Chinese jurisdiction, deeming India's activities there 'illegal and invalid'. India plans to invest $1 billion in constructing 12 hydropower stations in the area, sparking tensions. Both countries maintain conflicting views on the territory, with India considering Arunachal Pradesh integral to its land, while China insists it is part of southern Tibet. Recent discussions between Indian and Chinese foreign ministers aimed to address long-standing border disputes but did not resolve the current disagreement over development projects.
