China and India have been locked in a tense conflict along their Himalayan border since April 2020, when Chinese troops stealthily encroached upon some key borderlands in the northernmost Indian territory of Ladakh. More than three years later, the standoff between rival forces has solidified, with China continuing to frenetically erect new warfare infrastructure along the long frontier.

Even then, Chinese President Xi Jinping is expected to visit New Delhi next month for the Group of 20 summit, which is likely to be attended by other world leaders, from U.S. President Joe Biden and French President Emmanuel Macron to Prime Minister Fumio Kishida. Russian President Vladimir Putin’s appearance is uncertain given that the war in Ukraine appears to be at a pivotal stage.

The Sept. 9-10 summit raises the possibility that Xi’s trip could propel efforts for a deal to help defuse what has become an increasingly dangerous military confrontation between the nuclear-armed demographic titans. Both sides have forward deployed more and more lethal weapons.
