Why are the US and Russia discussing Ukraine peace negotiations without Ukrainian representation?

The US and Russia are engaging in discussions about restarting diplomatic relations and exploring tentative steps toward peace negotiations for Ukraine, notably without Ukrainian representation in those talks. This exclusion raises significant questions about the implications for Ukraine's sovereignty in decisions affecting its future. Among the key issues expected to be part of these negotiations are rare earths and critical minerals, which experts believe will be central to any agreement regardless of the negotiation format. These diplomatic developments are occurring amid rapidly evolving global events, highlighting tensions between major powers shaping potential peace terms.
