From: http://www.cnn.com/2015/08/04/china/china-winter-olympics-song-frozen/
This was an interesting article that intimates that because one of the songs China presented in its bid to host the 2022 Olympics sounds similar to Disney's Frozen, that it was the reason it gathered enough fans to let China win the bid. China, or many other countries are no stranger to copyright infringement, be it Thailand, Burma, or China. Ebay has tons of merchandise which are copies from other countries, be it garments, Lego clones, etc. But this is a pretty big news item as it is a government sponsored event.
