OPEC, non-OPEC fail to reach deal on output freeze

OPEC and non-OPEC producers on Sunday failed to reach a deal to freeze oil output, three oil industry sources told Reuters. Sources said OPEC producers had told non-OPEC members they needed first to reach a deal within OPEC, possibly at a June meeting. After that, the Organization of the Petroleum Exporting Countries will be able to invite other producers to join.
