Has any current western politician expressed concerns about a possible alliance between China and Russia?

At the moment we are witnessing a new conflict between Russia and the West which some people could compare and call a new Cold War. At the same time, the relations between China and the West are also not as good as they were and Pelosi's visit to Taiwan definitely hasn't improved it. In this situation, some kind of alliance between Russia and China seems likely. Some politicians like Kissinger or Lepen have expressed such concerns, but they don't have any political power. In this context, I am wondering if any current western politician (president or any member of government) has also expressed such concerns?
