Found this video of a song by the Canadian group Simple Plan featuring Chinese singer and television/radio host Kelly Cha (Zha Kexin; 查可欣).
Using a Chinese singer was a planned marketing tactic by Simple Plan (and/or their record company) to develop their international fanbase. In addition to this version of the song with Kelly Cha, there's also a version with Indonesian band KOTAK, a version with British singer Natasha Bedingfield. Apparently, Simple Plan has also featured other local artists performing the song in concerts when they've toured internationally. This seems like a pretty logical way of promoting a band in foreign markets and maybe such a simple plan makes a good marketing plan although there certainly might be some jet lag involved.
