Alizée-Nederland posted this video the other day. Alizée is talking about this upcoming event in China, and from a rough translation of the video, it looks like she is indeed going to China.
English Translation:
"Hello, this is Alizée. I am delighted to join you for the Dragon TV New Years' party at which I am to sing. I can't wait to discover Chinese culture and learn Chinese. December 31, I am waiting for you to celebrate the New Year 2022. See you soon, Dragon TV."
Here's what Wiki says about Dragon TV:
".....It is a satellite tv station.....Currently, Dragon TV's signal covers most of China, including Macau, Hong Kong, Taiwan and overseas in North America, Japan, Australia, Europe..."
