Canadian visiting South Korea to apply for Chinese Visa

Hi. I am a Canadian citizen currently in Korea as a visitor status. I do have an Alien Registration Card which was issued last August and is expired at the moment. I want to apply for a Chinese visa to visit a friend in Dalian, just for 3-4 days. Can I do this as a Canadian visitor in South Korea who has an expired Alien Registration Card? (I would go through extending the Alien Registration Card, but this process takes longer than my remaining time in Korea)
