China’s engagements across South Asia this October were defined less by new diplomatic initiatives and more by the implementation and testing of relationships already in motion. India stood apart as the summit between U.S. President Donald Trump and Chinese President Xi Jinping, as well as the aftermath of the BRICS summit, prompted renewed debate in New Delhi over its relationships with both Washington and Beijing. Elsewhere, established partnerships took more concrete forms. China announced their first joint army training with Pakistan, continued reconstruction assistance in Nepal and increased technology cooperation with Sri Lanka. Some more complicated tensions appeared in Nepal, where disrupted cross-border trade routes illustrated the vulnerabilities that accompany closer economic ties with China. Across the Indian Ocean’s island states, new export opportunities for Seychelles and continued outreach to the Maldives and Mauritius reflected China’s emphasis on trade and infrastructure as enduring channels of engagement. Together, those developments present a region in which China’s presence is increasingly visible.
