- Summary- No discussions about Russian price cap - delegates- Oil prices have come under pressure from weak economy- Next meetings to take place Feb. 1 and June 3-4LONDON/DUBAI, Dec 4 (Reuters) - OPEC+ agreed to stick to its oil output targets at a meeting on Sunday as the oil markets struggle to assess the impact of a slowing Chinese economy on demand and a G7 price cap on Russian oil on supply.On Friday, G7 nations and Australia agreed a $60 per barrel price cap on Russian seaborne crude oil in a move to deprive President Vladimir Putin of revenue while keeping Russian oil flowing to global markets.Many analysts and OPEC ministers have said the price cap is confusing and probably inefficient as Moscow has been selling most of its oil to countries like China and India, which have refused to condemn the war in Ukraine.Sources have told Reuters several OPEC+ members have expressed frustration at the cap saying the anti-market measure could ultimately be used by the West against any producer.JP Morgan said on Friday that OPEC+ could review production in the new year based on fresh data on Chinese demand trends and consumer compliance with price caps on Russia crude output and tanker flow."
