March 7 (Reuters) - Any decision to extend OPEC production cuts past June would have to include the continued participation by the non-OPEC members of the November accord, OPEC Secretary General Mohammad Barkindo said on Tuesday.
The group held talks in recent days with shale oil producers and hedge fund executives, he said during a media conference at the CERAWeek energy conference in Houston. This is the first time OPEC held bilateral meetings with shale producers and investment funds, Barkindo said.
"I think we have broken the ice between ourselves and the industry, particularly the tight oil producers and the hedge funds who have become major players in the oil market," he said in remarks on the sidelines of the energy conference. (Reporting by Marianna Parraga and Liz Hampton)
