For the thousands of frustrated travelers facing delayed and cancelled flights between Taiwan and its outlying Matsu Islands and Kinmen, there may have been a sense of déjà vu. Last week’s multi-domain Justice Mission 2025 exercises were not the first occasion on which China’s large-scale military drills have disrupted civilian air routes in the region. Yet the increasingly routine character of such exercises should not obscure their significance, nor the ways in which they are challenging long-standing cross-strait arrangements.
Beijing is, once again, testing a core element of the status quo that has underpinned a fragile peace across the Taiwan Strait for decades. This time, the focus is Taiwan’s contiguous zone – the 12-nautical-mile buffer surrounding its territorial waters. The steady normalization of People’s Liberation Army (PLA) military activity within this space marks a subtle but consequential shift, one that lowers thresholds, increases the risk of miscalculation, and sets a potentially destabilizing precedent for future Chinese military operations.
