My own experience is that yes, China is interested in the global anti-corruption movement. For a number of years China has chaired the International Association of Anti-Corruption Authorities, which is an association with affiliations to the United Nations' UNODC. It has provided them with support in terms of their governance and establishing that association in the first instance.
I do find that they are interested. They put on an annual anti-corruption seminar as well as an annual meeting, which usually has a workshop on the side. They get the anti-corruption authorities together, which would include the RCMP and quite a number of other countries in terms of participation.
