On December 9, Chinese and Russian military aircraft entered South Korea's Air Defense Identification Zone (KADIZ), prompting the South Korean military to deploy Air Force fighter jets and take tactical measures to prepare for any contingencies.
The Joint Chiefs of Staff announced that around 10 a.m. on the same day, seven Russian military aircraft and two Chinese military aircraft entered and then exited the KADIZ over the East Sea and South Sea in succession, adding that there was no violation of South Korean airspace.
The Joint Chiefs of Staff stated that the South Korean military had identified the Chinese and Russian military aircraft before they entered the KADIZ and deployed Air Force fighter jets to carry out tactical measures in preparation for any unexpected situations.
An Air Defense Identification Zone is a designated airspace established to detect and identify aircraft approaching a country's airspace at an early stage. Although it is not considered sovereign airspace under international law, it is customary for foreign aircraft to provide prior notification when entering such zones.
