The resolution on Sri Lanka is primarily led by the WEOG, the Western European and Other Group, along with the Eastern Europeans. In the UN context you have these regional groups. But it has attracted support from other regions, including Latin America.
I don't know the voting record of Brazil on this but I'm quite sure there was at least an abstention and also support from some other countries. Of course, the Chinese are not going to be keen for further human rights scrutiny in Sri Lanka, so they're not an emerging power that's going to be much help on this. It's interesting, though, that on November 18, right after the Commonwealth Heads of Government Meeting, they drew attention to the Sri Lankan government's need to be concerned about human rights—saying this for the first time ever, in a statement by the foreign minister on behalf of the foreign ministry of China—in its own way without outside interference. But it was still seen as a sign that they recognize the concern. Whether they'll act on it is a different matter.
I think what will be important for success in Sri Lanka is to undermine the Sri Lankan government's argument that this resolution is just western powers pandering to diaspora politics, or it's just because they don't like that fact they're losing power. There are lots of ways the government has characterized it. As long as India is on board it's very hard for the Sri Lankan government to make that characterization. You have India. You have some of the African countries and one or two of the Latin American countries. If you could get Japan, which has abstained, to join the vote at the council, that would be very important. That's the way to undermine this argument about this just being a western plot.
