LIVERPOOL, England, Dec. 11 (REUTERS) -- The world's wealthiest democracies will on Saturday (Dec 11) seek to present a united front against Russian aggression toward Ukraine when Britain hosts a meeting of foreign ministers in the northern English city of Liverpool.

The G7 meeting, attended in person by US Secretary of State Antony Blinken and his counterparts from France, Italy, Germany, Japan and Canada, comes amid international concern Russia could invade Ukraine. Russia denies planning any attack.

"What we have to do is deter Russia from taking that course of action," British foreign minister Liz Truss told reporters ahead of the talks.

"What the G7 meeting this weekend .. is about, is about a show of unity between like-minded major economies, that we are going to absolutely be strong in our stance against aggression, against aggression with respect to Ukraine."

Ukraine is at the centre of a crisis in East-West relations as it accuses Russia of massing tens of thousands of troops in preparation for a possible large-scale military offensive.

Russia accuses Ukraine and the United States of destabilising behaviour, and has said it needs security guarantees for its own protection.
