BEIJING, March 2 -- A Chinese spokesman on Sunday urged all sides involved in the Ukraine situation to comply with international law and seek a political solution to their disputes through dialogue and negotiations.

"China is deeply concerned with the current Ukraine situation," Foreign Ministry spokesman Qin Gang said when responding to a question on China's stance after Russia's upper house of parliament, the Federation Council, authorized President Vladimir Putin to use military forces to protect Russian citizens and soldiers in Ukrainian territory.

Condemning violences over the past days in Ukraine, Qin said China has been urging all parties in Ukraine to address their domestic disputes peacefully in accordance with the country's law, safeguard the legitimate rights of the Ukrainian people of all ethnics, and restore social order as soon as possible.

Qin said China always sticks to the principle of non-interference in any country's internal affairs and respects the independence, sovereignty and territorial integrity of Ukraine.

"There have been reasons for today's situation in Ukraine," said the spokesman, without detailing the reasons.

China will closely watch the development of the situation in Ukraine and calls on all sides concerned to respect international law and pursue a political solution to their disputes through dialogue and negotiations to safeguard peace and stability in the region, Qin said.
