"We remain ready to intensify actions including coordinated sectoral sanctions that will have an increasingly significant impact on the Russian economy, if Russia continues to escalate this situation," read the statement.

The G7 leaders will not participate in the planned G8 Sochi Summit and instead they will meet again in G7 format at the same time as planned, in June this year, in Brussels, according to the statement.

"We have also advised our Foreign Ministers not to attend the April meeting in Moscow. In addition, we have decided that G7 Energy Ministers will meet to discuss ways to strengthen our collective energy security," read the statement.
