Why blockading Taiwan is more than a food calculation

Could China starve Taiwan into submission with a kinetic blockade?

Theoretically, but hidden reserves, neutral shipping, global economic costs, and the likelihood of outside military intervention make it a strategically hazardous option.

A food reserve of less than 90 days is an unverified premise of this blockade scenario. Public information may leave uncertainty about stockpiles and resilience, so it cannot establish a dependable deadline for surrender. A blockade lasting several months would also allow time for other powers to assemble forces and would disrupt trade through the Taiwan Strait. Surface ships can board or divert traffic, whereas an aircraft enforcing the blockade with missiles has fewer ways to handle a neutral freighter. An attack on American-flagged shipping could expand the conflict and expose the blockading force to submarines and carrier aircraft. These are conditional scenarios, not a prediction of a fixed intervention timetable.
