Mars Wrigley, the manufacturer of the Snickers candy bar, apologized Friday for promotional material that referred to Taiwan as its own country.

The American candy-maker had been promoting what appeared to be an online event with the South Korean boy band BTS in a video on social media. The video, meant for audiences outside China, said attendance was restricted to people of certain countries, and included a flag of Taiwan…

After several nationalistic influencers shared a screenshot of the Snickers promotional video on Weibo, a popular Chinese social media site, thousands of Chinese internet users slammed it for describing Taiwan as a country, and some threatened to boycott the brand.

The social media firestorm prompted Mars Wrigley to issue two apologies on Friday. The company said it had reached out to its regional team in Asia to ask that the language be adjusted.
