so apparently, this did happen, you can find the newscast here
it's mostly about 525/138's visit to Vladivostok, they interviewed a couple of admirals about the ships. It talked about a bunch of stuff about the exercise.
They talked about 138 a little bit. The Chinese name of Sov is "modern", I'm guessing that's the original Russian name for that too. So, that confused the interviewer a little bit.
they said about 525 has very good ASW capability, has hull mounted sonar, Towed sonar, ASW helicopter, ASW rockets, torpedoes and Rocket assisted torpedoes (see I think it sounds like ASROC here). You have to listen to past half way through the interview to get to this part.
