Which country is NOT participating in the "Sea Dragon 2025" naval exercise?

The Sea Dragon 2025 naval exercise was conducted from March 6-19, 2025, off the coast of Guam in the western Pacific Ocean. The participating nations included India, Japan, Australia, South Korea, and the United States (host nation through its 7th Fleet). New Zealand is not participating in the 2025 edition. This multilateral maritime warfare drill focuses on improving interoperability, maritime security, and submarine tracking techniques. Each participating country deploys Maritime Patrol and Reconnaissance Aircraft (MPRA), with India utilizing its P-8I aircraft. The exercise features a grading system with the top performer receiving the Dragon Belt Award, which Japan has consistently won since 2022. The Sea Dragon exercise began in 2019 as a bilateral drill between the U.S. and Australia but has since expanded to include multiple nations.
