China imposed sanctions on seven US military firms and their executives on Friday following a recent US arms sale to Taiwan.

The Chinese Foreign Ministry stated that it froze the sanctioned firms’ and executives’ assets that were located within Chinese jurisdiction. The ministry also prohibited all Chinese organizations and individuals from engaging in any transactions or cooperation with the companies and individuals.

The ministry claimed that the firms’ recent military aid and arms sales to Taiwan violated the one-China principle and interfered in China’s internal affairs, asserting that the actions undermined China’s sovereignty and territorial integrity.

On December 21, the Biden administration approved a substantial military aid package worth $571.3 million for Taiwan. That same day, the US State Department approved a $295 million arms sale to Taiwan.

The move by China underscores the escalating tensions between the two nations over Taiwan’s defense and sovereignty. This latest round of sanctions follows measures China took against at least 13 US defense firms earlier in December for similar reasons. The Chinese government has consistently reacted strongly to US military support for Taiwan, which it views as a direct challenge to its claims over the island. The US, while not officially recognizing Taiwan as a separate state, has maintained a policy of strategic ambiguity and is Taiwan’s largest arms supplier.

The context surrounding the current situation between China and Taiwan illustrates a complex geopolitical landscape characterized by historical tensions. Since the conclusion of the Chinese Civil War in 1949, Taiwan has functioned as a self-governing entity. The People’s Republic of China (PRC), however, has consistently maintained its claim over the island, asserting that it is an integral part of its territory. The PRC has never renounced the possibility of using force to achieve reunification with Taiwan. In recent years, China’s military activities around Taiwan have intensified, including frequent military drills and incursions into Taiwan’s air defense identification zone (ADIZ).

The US has responded to these developments by increasing its military cooperation with Taiwan, including arms sales and joint military exercises. This support is essential for Taiwan’s defense capabilities amid growing concerns about China’s assertiveness in the region. As tensions continue to rise, both sides remain entrenched in their positions. China’s sanctions against US firms are expected to strain relations between Beijing and Washington further, complicating efforts for diplomatic engagement.
