Mostly True
A petition campaign in Gwangju calling for coexistence (상생, "sangsaeng") with the Yongin semiconductor cluster has gathered 20,000 signatures, according to sources reviewed for this report.
The campaign centers on a request that the interests of Gwangju residents be reflected in the development of the Yongin semiconductor cluster — the large-scale semiconductor manufacturing complex being pushed in Yongin, Gyeonggi Province. The 20,000-signature figure was stated in the claim and was supported by the sources reviewed; no source was skipped due to captchas, authentication barriers, or blocking, with all original documents accessible.
The reviewed materials do not establish details beyond the signature count and the coexistence demand itself, such as whether the signatures have been formally delivered to a specific institution or what concrete response has followed. Those points should be treated as unconfirmed.
The claim as put forward holds up against the reviewed evidence, making the overall assessment: Verdict: Mostly True
