India lodged a diplomatic protest with China over the latter’s release of an official map claiming territory in the Indian state of Arunachal Pradesh and Aksai Chin, intensifying existing border tensions between the two nations, especially as a major summit is scheduled for next month.

Both leaders are expected to attend the G20 gathering in New Delhi, where the border issue will likely be a key topic.
