Q: In the Chinese visa form it says

Applicants who were born in Turkey or who have travelled to Turkey must provide an original personal letter. This letter should state the detailed reasons for travel to Turkey and specify the exact date(s) of entry, exit, and duration of the stay(s). Additionally, a photocopy of the Turkey visa (if applicable) and all entry and exit stamps must be provided.

I'm curious why a Chinese visa needs a personal explanation about visits to Turkey.
Would visits to Turkey before China be a negative point when applying for a Chinese visa?

A:
Why does the Chinese visa form specifically ask about visits to Turkey?
