BEIJING — China lacks enough snow for the 2022 Winter Olympic Games, environmentalists said. China is too repressive to hold the Games, detaining hundreds of lawyers just in the past month, rights campaigners said. On Friday, despite those complaints, the International Olympic Committee awarded the Games to Beijing.

Now some people are drawing attention to what may be a third early problem, one that could entangle China in a dispute with the Walt Disney Company or at least attract ridicule. An official song of the Games, “The Snow and Ice Dance,” they asserted, is suspiciously similar to “Let It Go,” the wildly popular ballad sung by Idina Menzel in the Disney animated film “Frozen.”

On the YouTube page for “The Snow and Ice Dance,” one of 10 official songs of the Games, many of the comments were in Chinese, although it was not clear how many of them came from the mainland, where an official ban on the site makes access difficult. A number of commenters struck a surprised or sarcastic note:

“I nearly sang ‘Let it Go!’ ” wrote Zeta Fera.

“Rubbish country,” wrote leckylecky. “Only understands how to copy copy copy.”
