MTECHTIPS:- Crude prices dropped in Asia on Monday as investors noted China PMI figures released at the weekend showed expansion and as details are awaited on an OPEC plan to curb crude output. On the New York Mercantile Exchange, crude oil for delivery in November fell 0.87% to $47.82 a barrel. Markets in China are shut for a week-long holiday.
