What is one great contribution that my contry made to the world?

When most countries suffer a natural disaster we most times come to their aid by sending doctors, firefighters and volunteers to help people. Examples of some of Korea's relief effort include the China Sichuan earthquake, Nepal earthquake, Indonesia tsunami etc. We also coutributed relief and aid for the Japan tsunami. The nuclear plant collapsed due to the effect of the tsunami. It was terrible accident. GREAT JOB!
