Put the ring in a box with the words "I Love You" written on little strips of paper in several different languages. Practice saying the phrase in each language and then actually ask her multiple times.
Take her on an exotic trip to another country. While there, plan an intimate night that ends with a romantic proposal.
Take her out for a Chinese dinner and give her a custom made fortune cookie that says 'Will you marry me?'. When she opens it, give her the ring and pop the question.
