Beta news agency quoted Hua Jiang as saying that Ahtisaari would attend the Security Council session to submit his report and speak about the progress achieved in the negotiating process and future steps.
Hua Jiang recalled that the only time framework was imposed by the Contact group for Kosovo which requested that the negotiations be completed by the end of the year.
The final decision on Kosovo's future will not be made by Ahtisaari, but by the Contact group and the UN Security Council, she said, adding that those who believed that criticising Ahtisaari would stop or postpone the process were mistaken.
