I feel like I already answered that in the last paragraph.
It’s litterally anything that whitewashes anything the CCP does. Maybe it’s justification for island building in the South China Sea, framing international right of way passages through the same body of water as border incursions, trying to reduce support for weapon sales to Taiwain, or trying to reduce allied responses to an invasion of Taiwan. It could also just be spreading general unrest.
Unsupported stone isn’t all that strong.
