Wong also flagged meeting her Chinese counterpart at the G20 summit on the Indonesian island of Bali later this year.
In a speech in Singapore on Wednesday night, Wong said China should use its strong links with Russia to lobby for an end to the fighting.
She said it was vital that powerful countries should “exert their influence” on Russian President Vladimir Putin to end the conflict.
“This includes China, as a great power, a permanent member of the (United Nations) Security Council, and with its ‘no-limits partnership’ with Russia,” Wong said at an event organised by the International Institute for Strategic Studies think tank.
“Exerting such influence would do a great deal to build confidence in our own region.
“The region and the world is now looking at Beijing’s actions in relation to Ukraine.”
China has refused to criticise Russia’s invasion of Ukraine or even to refer to it in such terms, while accusing NATO and the West of provoking Moscow into attacking.
Xi told Putin that “all parties should responsibly push for a proper settlement of the Ukraine crisis,” according to the official Xinhua News Agency.
Xi “noted the legitimacy of the actions taken by Russia to protect the fundamental national interests in the face of challenges to its security created by external forces,” according to Moscow’s official readout.
Wong also urged China to show moderation in its relations with its own neighbours in the Pacific, stressing that would “give the region and the world greater confidence”.
She did not confirm if a meeting between her and Chinese Foreign Minister Wang Yi had been scheduled for Bali in November but said the federal government was “open to engagement” with China.
