I do believe both of these stations run (or did run) China Radio International.
CRI has a history (even though I do believe they can now legally buy their own US radio stations) of renting first via LMA in a market, then buying the stations via a 3rd party Chinese-American citizen. Would not surprise me if this is what’s happening—though I can’t confirm currently as I don’t want to sift through the FCC records and I’m not shelling out the scratch for RBR.
What I’d be curious about is what the incentive is for a Chinese-American citizen to buy a station and use it to rebroadcast a non-commercial format from their native land. Either CRI is exceptionally well-liked by the expat community here or there’s some sort of cash/promotional considerations given by the Chinese Government to buy and maintain these stations. I’m going with the latter...assuming they are being “sold” to CRI via a private citizen.
