Russian President Vladimir Putin and the Chinese foreign ministry both said on Wednesday they are concerned by political unrest taking place in neighboring Kyrgyzstan and hoped for a swift return to stability.
The government there has been toppled in the civil unrest that started Monday.
Russia also gave assurances it was in touch with all the sides in the conflict and hoped that democratic process would be restored.
Those announcements came as the prime minister was forced to quit and recent parliamentary elections were annulled.
Protesters had earlier broken into a hotel where parliament was meeting, resulting the man who could be the next prime minister to flee.
Sadyr Zhaparov had only been freed from prison hours earlier by protesters representing one group to assume the role, but he later confirmed on television he did not yet have the backing of all parties.
Cracks have also started to appear in the opposition parties. Those recent elections results sparked their protests -- but now at least three distinct groups have attempted to claim leadership, potentially sparking further tensions.
Kyrgyzstan borders China and also hosts a Russian military base.
There were further scuffles overnight between vigilantes and protesters in the capital Bishkek. They again tried to force their way into government buildings or attacked shops and restaurants, according to local news reports.
