Episode Description from the Publisher

On July 6 China tested a submarine-launched intercontinental ballistic missile into the South China Sea. A PLA statement after the test claimed that “the missile test was a routine part of China’s annual military training program, and relevant countries had been notified in advance.” In this episode of The Diplomat’s Asia Geopolitics Podcast hosts Ankit Panda and Katie Putz take stock of the test and the reactions across the Pacific. The July 6 was the first time that China has launched a submarine-launched ballistic missile into international waters, and only its the second launch of a ballistic missile into international waters since 1980. Also unusual: China provided notice to Australia, Japan, the U.S. and others, through in some cases only half an hour.You can subscribe to The Diplomat’s Asia Geopolitics podcast on Apple Podcasts and Spotify; and watch the episode on YouTube.
