Crude prices edged down on Friday as U.S. crude inventories remained heavy last week and investors were cautious about the possible outcomes of this year\'s last bipartisan meeting in Washington over the \"fiscal cliff.\" U.S. President Barack Obama met with a bi-partisan group of congressional leaders at the White House at 3:00 p.m. on Friday, trying to reach a deal before the deadline of Jan. 1. If there was no deal, automatic spending cuts and tax hikes would come into force, which according to economists could drag the world\'s largest economy back into recession. Investors remained cautious before the lawmakers\' last-ditch attempt in avoiding \"fiscal cliff,\" while the trading volume stayed light.
