Mongolia's Communist Party re-elected its reform-minded chairman but replaced most other party chiefs in its latest leadership shake-up, China's official Xinhua News Agency reported Friday.

The presidium, the top body of the Mongolian People's Revolutionary Party, has undergone several major changes this year amid public pressure to adopt reforms similar to those being introduced in the Soviet Union.Party chairman Gombojavyn Ochirbat was re-elected and L. Tudev, director of the party newspaper Unen, was reported to have retained his presidium seat.
