Still very much in the research stage. China has one experimental Molten Salt Reactor that was supposed to start up last year, but I'm not sure what's happening to it right now. If everything went as planned that would be the only operating thorium-fueled nuclear plant in the world. I think they are expecting to have commercially ready designs by 2030.
India has a plan based on a three-stage fuel cycle, where the third stage runs on thorium. However they've had significant delays and the first prototype breeder reactor of the second stage is projected to be finished at the end of this year. The third stage is probably still some years away.
India and China are probably the most ambitious in terms of thorium fuel cycle research. India has the world's largest thorium reserves, and hope to utilize it for their power generation. China's most pressing concern is their smog crisis, which they hope to solve partly with nuclear power. They are also aiming to own most of the intellectual property with regards to thorium reactors, and it is part of Xi Jinping's drive toward making China carbon neutral by 2060.
Other countries have some small research initiatives but no concrete plans to build anything so far as I know.
