Pakistan looks to be next. There will likely be some debt renegotiation and a bailout, attached with some pretty onerous terms I'm sure. A possible bad path is if the US decides to make an example out of Sri Lanka because it went all in on China's debt trap diplomacy. Does Sri Lanka occupy a strategic location on the busiest sea lanes? If so, then there may be some competition between China and the Quad that may play out in an interesting way.
