LONDON, Dec 1 (Reuters) - As a U.S. envoy heads to Moscow to negotiate over a complex blueprint for peace in Ukraine, Russian Nobel Peace Prize winner Dmitry Muratov says a vital element is missing from the agenda.

Borders, security guarantees, the fate of frozen Russian assets and the prospects for joint U.S.-Russian investment ventures are all expected to be on the table when President Donald Trump's envoy Steve Witkoff sits down with President Vladimir Putin in the Kremlin on Tuesday.
