It’s a little funny but redlines / final warnings have a “different meaning” in PRC’s diplomatic language e.g. https://en.wikipedia.org/wiki/China%27s_final_warning

The actual diplomatic language for war is “勿谓言之不预” (from official diplomatic channels) and they use “core interests” for a vaguely defined redlines: https://www.strategictranslation.org/glossary/core-interests

So yes, cross “redlines” won’t trigger a war with PRC. And ignoring final warning is also fine.
