OPEC and Russia will meet in Saudi Arabia this week after all but banishing a global oil glut. While looming political crises threaten to tighten supplies further, the group seems determined to keep its cuts in place, Bloomberg reports.

Almost 16 months of output curbs by the Organization of Petroleum Exporting Countries and its partners have seen crude rally to a three-year high near $70 a barrel. That’s replenishing their coffers after the worst oil slump in a generation, encouraging the producers to extend their intervention even as Venezuela’s petro-economy implodes and Donald Trump threatens Iran with sanctions.

While analysts warn that price gains could backfire on OPEC by spurring rival U.S. supplies or crimping demand, ministers gathering in Jeddah on April 20 will focus on ways of prolonging their cooperation. That could include new inventory targets that extend the cuts, and laying the foundations for an alliance that will last for years. Any recommendations this week would have to be ratified at the group’s full meeting in June.
