Russia is not willing to share anything, really. Neither Russia nor China provides very much public access to any information it holds.
What are their intentions? The reason I emphasized avoiding heavily militarized or provocative responses is that from my perspective, Russia and China are both trying hard to depict the west as weaponizing outer space, and I see some of the responses that are pursued as playing into that hand.
Globally, it is essential at the United Nations that space remains peaceful. That is a fundamental goal of that body and of many state participants, and the perspective that there are active efforts in the west to weaponize space is driving a lot of conversation and competition among allies, diplomatic allies in particular, regarding some of these issues.
My perspective is that it's not clear what states are doing. It's clear that a lot of capabilities are being developed and technologies are being tested. It is not at all clear what the intentions are behind them and which ones will actually be developed, deployed and put into orbit, if any. That includes the intelligence on nuclear, as well as other potential kinetic capabilities.
Given that lack of clarity, we need to exercise leadership in trying to lower the volume.
