Taiwan's Ministry of Defence has said it tracked six Chinese military aircraft and two naval vessels around Taiwan between 6 a.m. on Sunday and 6 a.m. on Monday, media reports said.

Of the six People’s Liberation Army (PLA) aircraft, one Shaanxi Y-8 anti-submarine warfare plane entered the southwest corner of Taiwan’s air defence identification zone (ADIZ), according to the MND as quoted by Taiwan News.

Responding to the development, Taiwan sent aircraft and naval ships and deployed air defence missile systems to monitor PLA activity.

In addition, the MND tracked two Chinese balloons at 9:03 a.m. and 2:43 p.m., respectively, on Sunday crossing the Taiwan Strait median line in the northeast sector of the ADIZ, around 110 nautical miles (204 km) northwest of Keelung at altitudes of around 8,230 meters. The balloons headed east and disappeared at 9:36 a.m. and 4:35 p.m, reported Taiwan News.
