SEOUL, Oct. 10 (Yonhap) -- South Korea spends around 30 million won (US$ 26,525) every time it scrambles fighters to respond to intrusions by Chinese military planes of the Korea Air Defense Identification Zone (KADIZ), a lawmaker said Wednesday citing a defense ministry report.

The Air Force immediately sends fighters and issues a warning message when foreign military aircraft enter the air defense zone without prior notification.

According to the report submitted to Rep. Kim Joong-ro of the minor opposition Bareunmirae Party, scrambling a fighter jet costs about 3 million won, including expenditure on parts and fuel. South Korea usually sends 10 fighters when Chinese aircraft remain inside the KADIZ for four hours.

This year, China violated the KADIZ over the East Sea five times, causing South Korea to spend 150 million won.

Kim has asked the government to reach an agreement with Beijing under which each side gives prior notification before its military aircraft enter the other's air defense identification zone, as with a 2012 deal with Japan, so that neither side need scramble planes.

South Korea and China signed a deal in 2008 to operate telephone hotlines between their navies and air forces, but the agreement didn't cover this issue.
