China must continue to enforce its one-child policy until new rules allowing all couples to have two children go into effect, the top family planning body said.

The ruling Communist Party said last week that Beijing would loosen its decades-old one-child policy. The plan for the change must be approved by the rubber-stamp parliament during its annual session in March.

Several parents interviewed by Reuters were lukewarm about the idea of having a second child after the new policy was announced last week.
