Mr Wallace extended an invitation to his Russian counterpart, Sergei Shoigu to visit London to discuss mutual security earlier this week.
Mr Shoigu has offered to meet in Moscow instead, given the last bilateral defence talks between the countries took place in London.
A senior defence source said: “The Defence Secretary is glad that Russia has accepted the invitation to talk with his counterpart.
“Given the last defence bilateral between our two countries took place in London in 2013, Russian defence minister Sergei Shoigu has offered to meet in Moscow instead.
“The Secretary of State has been clear that he will explore all avenues to achieve stability and a resolution to the Ukraine crisis. We are in communication with the Russian government.”
It comes after Downing Street warned Russia would be “punished” if the country pushes ahead with any “destabilising action” in Ukraine.
Commons Defence Committee chairman Tobias Ellwood warned a Russian incursion could be “imminent” as President Vladimir Putin looked to exploit Western weakness.
“Putin is taking full advantage of a weakened West. We are looking risk-averse, somewhat timid,” he told the BBC Radio 4 Today programme.
“Putin’s ultimatum demanding Nato push back, of course that was dismissed but that’s given him the pretext to say that there is an aggressor and that he must act.
“We see these combat-ready troop formations. He has actually boxed himself into a corner because so much effort has been put into this.
“He also recognises that he will never again be as strong as this to take advantage of the West’s weakness. I suspect that an invasion is now imminent.”
US secretary of state Antony Blinken held talks with Russian diplomats in Switzerland on Friday in a bid to avert a conflict on Ukraine’s border, where Moscow has amassed an estimated 100,000 troops.
Number 10 said if Russian president Vladimir Putin launches an offensive, there will be a “package of sweeping measures” launched by the UK and its allies against the Kremlin.
Earlier, Foreign Secretary Liz Truss warned Mr Putin he must “desist and step back” from war in Ukraine or risk being dragged into a prolonged conflict like the Soviet invasion of Afghanistan.
Speaking at the Lowy Institute in Sydney, she said: “If there is an incursion by Russia into Ukraine, it would come at a massive cost.
“We are prepared to put very severe sanctions in place, we are also working to support Ukraine in terms of defensive capability.”
The chairman of the Foreign Affairs committee said that the UK should be ready to give Ukraine financial support.
Tom Tugendhat told BBC Breakfast that Ukraine needs money to be prepared for an invasion.
“I’d like to see all of us going further, because one of the things that’s delaying the ability of the Ukrainian people to mobilise their armed forces to meet any such invasion is, that has a huge effect on any country’s economy,” he said.
“If you take hundreds of thousands of people out of the workforce in order to stand guard they will have a real impact on jobs and lives in other sectors.
“We saw that over lockdown over the last couple of years – the impact that has. So, we need to be ready to support the Ukrainian people financially as well, and that may be with loan guarantees and things like that.”
A spokesman for Boris Johnson said: “I think the Prime Minister has been clear that any destabilising action by Russia in Ukraine would be a strategic mistake and would have significant consequences.
“I’ve talked about the fact that we’re working closely with our partners, including the US, to draw up a package of sweeping measures to make sure that the Russian government is punished if it crosses the line.”
