What the rule actually says
China's foreign-teacher work permit system asks provincial foreign affairs offices to verify that an applicant is a native speaker of the language they'll teach, and in practice this is implemented as a passport check against a short list of countries — most commonly the US, UK, Canada, Australia, New Zealand, Ireland and South Africa. If your passport isn't on that list, the standard Z visa route for a foreign English teacher post is not available to you, regardless of your fluency, IELTS score, or teaching ability.
This is different from many Southeast Asian markets, where hiring rules leave more room for employer discretion. In China, the restriction sits with the government approval step, not just the school's preference, so a sympathetic principal generally can't work around it for a standard teaching post.
