The extension of the talks is supported by all parties, Wang Qun said on Friday.
However, he said, “The deadline has not been coordinated yet.”
China is inspired by progress that the parties succeeded in achieving during the talks in Vienna, Wang Qun said.
At the same time, he said, “Certain disagreements remain. It is necessary to continue the work.”
