Fourth Taiwan Strait Crisis

The Fourth Taiwan Strait Crisis (traditional Chinese: 第四次台海危機; simplified Chinese: 第四次台海危机) is an ongoing conflict between the People's Republic of China (PRC) and Taiwan, officially the Republic of China (ROC), with the PRC conducting several large-scale military exercises that encircled Taiwan. China initiated military maneuvers around Taiwan on 2 August 2022, before launching their first major military drill on 4–11 August 2022, which was carried out by China in response to US Speaker of the House Nancy Pelosi's visit to Taiwan. The drills involved live-fire drills, air sorties, naval deployments, and ballistic missile launches by the People's Liberation Army (PLA), marking China's biggest escalation in the region since the Third Taiwan Strait Crisis in 1996.

China's military drills were shows of force intended to deter what the PRC perceives as US meddling in its internal affairs, and to demonstrate Chinese military power in the region for both international and domestic audiences. The drills drew backlash from the G7 (Group of 7) nations. The live-fire drills observed during the seminal August 2022 military exercise were unprecedented in recent history, and took place in seven zones that surrounded the island's busiest international waterways and aviation routes. The first drill came to an end on 11 August 2022.

Since then, China has launched at least seven more major military drills targeting Taiwan, with PLA exercises, maritime patrols and even Coast Guard boardings around the Taiwan Strait becoming routine in what has been defined as "grey-zone tactics". The PRC also declared sovereignty over all airspace above and around the island, publicly renouncing the Davis line, an imaginary median line across the Taiwan Strait that previously marked the de facto territorial waters between the mainland and the island of Taiwan since the 1950s until 2019.
