TOKYO — Eager to position India as a leading Asian power to rival China, Prime Minister Narendra Modi has prioritized strengthening ties with Sri Lanka and other nearby countries. However, political developments in neighboring nations, along with some misguided diplomacy from New Delhi, are undermining the leader’s efforts.

In Sri Lanka, antiestablishment lawmaker Anura Kumara Dissanayake won the presidential election on Sept. 21. However, the coalition led by his Janatha Vimukthi Peramuna (JVP) party secured only three of the 225 seats in parliament, prompting Dissanayake to dissolve the legislature and call a general election for Nov. 14.
