Taiwan
In response to mainland China's purchase of the Su-27, the Republic of China (Taiwan) entered into talks with the US and France about the possible purchase of new fighters. While the US would oppose Taiwan's acquisition of the Mirage 2000 and instead pressure it to procure the F-16, in November 1992, the
Republic of China Air Force became the first customer for the Mirage 2000-5. The order for 48 single-seat Mirage 2000-5EIs and 12 Mirage 2000-5DI trainers was condemned by China. The aircraft order also included 480 Magic short-range air-to-air missiles, 960 MICA intermediate-range air-to-air missiles, auxiliary fuel tanks, ground support equipment, and monitoring equipment; total costs amounted to US$4.9 billion, of which $2.6 billion was for the aircraft.
[91] The MICA missile provides the Mirage with a degree of
BVR capability needed for its role as front-line interceptor. In addition, a set of
ASTAC electronic intelligence (ELINT) pods was ordered.[

DEFA 554 cannons were also acquired and fitted on the two-seaters, as they do not have an internal gun armament.
Taiwanese Air Force Mirage 2000-5EI
Taiwanese Mirage 2000s were delivered from May 1997 to November 1998, and are based at Hsinchu AB.[

After the presence of cracks in the blades of the aircraft's engines were detected in 2009, Dassault worked with Taiwanese authorities to successfully rectify the issue and provided compensation for the engine damage. By the following year, normal training hours of 15 per month had resumed and the fleet's operational readiness had been restored, after having reportedly dropped to 6 hours per month because of the engine troubles.
[92][93] In addition, there were considerations of mothballing the entire Mirage fleet because of its high maintenance costs.
[94] Although the aircraft's maintenance supplies cost more than those of the Republic's
AIDC F-CK-1 Ching-kuo and the
Lockheed F-16 Fighting Falcon, the fleet was reportedly[
