RRI.CO.ID, Jakarta – Indonesia's Ministry of Foreign Affairs is closely monitoring developments following China's long-range ballistic missile test launched from a nuclear-powered submarine in the Pacific Ocean earlier this week.

Foreign Ministry Spokesperson Yvonne Mewengkang said Indonesia had received prior notification from the Chinese government regarding the missile test. According to her, such notification is an important transparency practice and serves as a Confidence-Building Measure (CBM).

"The information we have received indicates that the government of the People's Republic of China provided prior notification. This is important because transparency and the provision of notification are important Confidence-Building Measures," Yvonne told reporters after a press briefing in Jakarta on Thursday, July 9, 2026.

Yvonne explained that, in principle, international law does not contain a general prohibition on the possession or testing of ballistic missiles.

"To our knowledge, there is no general prohibition under international law on the possession of ballistic missiles," she said.

The Chinese Navy conducted the long-range ballistic missile test from a nuclear-powered submarine in the South Pacific on Monday, July 6, 2026.

Chinese state media reported that the missile, carrying a dummy warhead, was launched at 12:01 p.m. local time and landed in a designated area of the ocean, without disclosing either the launch site or the type of missile used.

Several defense analysts believe the missile tested was either a JL-2 or JL-3 submarine-launched intercontinental ballistic missile (ICBM) fired from a Type 094A nuclear-powered ballistic missile submarine.

The launch marked the first ballistic missile test from a Chinese nuclear-powered submarine since 2024. In that previous test, China launched an intercontinental ballistic missile into waters near French Polynesia in the Pacific Ocean, marking its first launch toward that area since 1980.

The Chinese government said the missile test was part of their routine annual military exercises, carried out in line with international law, and was not directed at any specific country or target.
