When building and upgrading the own strength，China should pay more attention to soft power diplomacy. China must convince the world that it is becoming a better superpower and will ensure a more prosperous and peaceful world. China can increase its soft power by investing in global public goods，such as providing public goods that people and governments around the world need but cannot get on their own. By promoting common economic development，safeguarding and improving public education and health，coping with climate change，and maintaining an open and stable international economic system，China’s existence as a superpower in the 21^st century will be regarded as a regional and world’s well-being. Soft power is the ability to get the desired results through attraction. Therefore，diplomacy through education and culture is a strategic way to enhance China’s soft power. In concerned with China-Indonesia relations，it is urgent to strengthen the educational and cultural cooperation between China and Indonesia.
