Well I think none of the foreign assistance should be mentioned especially the US rolesince it is either limited debatable or indirect If foreign assistance is mentioned it should be something extensive and nondebatable like the Chinese or North Vietnamese role However there is no point making the section too long or undue by extensively discussing the Chinese Vietnamese or US role other than mentioning that Vietnam overthrew them Extensive views on foreign roles are already on the main page regarding these topics I have no opinion on the rest of the Cambodia selection It seems mostly fine to me
