What does CTC stand for in China?

Could you please clarify the acronym "CTC" in the context of China? I'm aware that abbreviations can have multiple meanings depending on the field or region. Is it related to a specific industry, such as finance, technology, or healthcare? Or perhaps it's a government initiative? I'd appreciate if you could elaborate on the background or context surrounding this acronym, as it would help me provide a more accurate answer. Thank you for your question and I'm looking forward to understanding the significance of "CTC" in China.
