Key assessment
The G7 warning gives diplomatic weight to concerns about access east of Taiwan, but it does not establish that China has imposed a blockade. Taiwanese officials' assessment that China is practising for one is consequential: coordinated military, paramilitary and civilian activity could develop options for restricting access without a declared blockade.
The supplied evidence does not establish that the regular coast guard patrols are coordinated with other assets or prove their purpose. Verified changes in the composition and coordination of activity would help test the officials' assessment.
What happened
G7 foreign ministers warned in a declaration published on 11 November that increasingly assertive Chinese activity east of Taiwan threatened regional stability, freedom of navigation and the safety of international shipping. The ministers and the EU high representative met in Paris on 9 and 10 November.
The declaration opposed unilateral changes to the cross-strait status quo, particularly through force, coercion or their threat. Taiwanese officials say they believe China is practising for a potential maritime blockade using military, paramilitary and civilian assets.
- Reporting on 12 November 2026 described regular Chinese coast guard patrols east of Taiwan since June 2026.
- Taiwan regards waters east of the island as critical to supply routes from allies in a blockade or conflict.
Why it matters
Taiwan regards its eastern waters as critical to receiving supplies from allies during a blockade or conflict. Any future interference there could constrain access to the island and expose international shipping to disruption. The evidence does not establish that a blockade is underway or that shipping has already been disrupted.
What to watch
Key questions
- Do verified observations show changes in the frequency, location or composition of Chinese patrols east of Taiwan?
- Do Chinese military, paramilitary and civilian assets conduct coordinated activity consistent with the blockade practice described by Taiwanese officials?
Implications
Military & Security
Regular Chinese coast guard patrols east of Taiwan add to security pressure in waters Taiwan considers important for access during a blockade or conflict.
Diplomacy
The G7's joint warning publicly sharpens diplomatic concern about Chinese activity and opposition to coercive changes to the cross-strait status quo.
Trade & Supply Chains
The activity raises concern about potential disruption to international shipping and routes Taiwan considers critical for allied supplies, although no actual disruption is established.
