Oil slips on fears over higher OPEC supply, slower China demand

Oil prices slipped on Tuesday as expectations that top producers would agree to raise oil supply in a meeting this week weighed on sentiment, already hit by concerns over slowing Chinese demand.
Brent crude dropped 14 cents or 0.2% to $63.55 a barrel by 1145 GMT, after losing 1.1% the previous day. US West Texas Intermediate (WTI) crude fell 2 cents to $60.62 a barrel, having lost 1.4% on Monday.

They both touched the lowest in more than 6 days, extending losses that started late last week.
Expectations that the Organization of the Petroleum Exporting Countries and its allies, a group known as OPEC+, would boost oil output from April are pushing prices lower.
