Taiwan's defense ministry said it detected 24 Chinese air force planes operating around the island and carrying out "joint combat readiness patrols" with Chinese warships on Wednesday, the first large-scale military activity after the Taiwanese election.

China, which views Taiwan as its own territory, has over the past four years regularly sent warplanes and warships into the skies and waters around the island as it seeks to assert sovereignty claims that the Taipei government rejects.

Taiwanese voted for the ruling Democratic Progressive Party's (DPP) Lai Ching-te as its next president on Saturday, a man Beijing has repeatedly blasted as a dangerous separatist and bringer of war.
