It is the non-interference in internal affairs policy. China is having it to criticize the US gunboat approach. It is not a policy that will be used forever. See how Haiti was criticized by China for its internal affairs just a few weeks ago.

I tried to look at Google News, I don't see anything related.
China complained about the fund provided by the UN being abused by the Haiti government. If there is no fund, there will be no complaint.
