Certainly China has included the Arctic as part of its polar silk road plans and has expressed a desire to be a polar great power. It has recently backed off from its narrative about being a near-Arctic state. I think China was realizing that it was not in an effective advocacy position. It still wants to be a global power, and to be a global power, the Arctic is part of its planning.
I can turn to my colleagues if they want to add anything else, but I'll leave it at that.
