Indonesia and South Korea pledged Friday to strengthen their collaboration in developing military equipment as Jakartas defense minister Purnomo Yusgiantoro hosted his counterpart Kim Kwan-Jin. We learn from Korea how to be independent. There is no such thing as a strong country if its defence industry is not strong, Yusgiantoro said, adding the partnership was solid because Seoul was sincere in its transfer of technology. Indonesia agreed in July to join a South Korean project to develop fighter jets. It has also chosen South Korea as preferred bidder for its T-50 Golden Eagle supersonic trainer jet project, despite a reported attempt by Seouls spies to steal secrets from the project from a visiting Jakarta delegation in February.
