The European Union is pressing ahead with a ninth sanctions package on Russia in response to Moscow's attack on Ukraine.
Making the announcement at a news conference in Finland on Thursday, European Commission chief Ursula von der Leyen said the EU was working hard to hit Russia where it hurts and to reduce even further its capacity to wage war on Ukraine.
Von der Leyen did not provide details of what measures a new round of EU sanctions could entail.
The EU last month gave a final approval to its eighth batch of sanctions over the invasion, including more restrictions on trade in steel and tech products.
At the joint news conference with the prime ministers of Finland and Estonia, and the deputy prime minister of Sweden, Von der Leyen said Russia's attacks on Ukrainian civilian infrastructure such as power supply amounted to war crimes.
The European Parliament on Wednesday designated Russia a state sponsor of terrorism, arguing that its military strikes on Ukrainian civilian targets violated international law.
Russia denies deliberately targeting civilians in Ukraine but acknowledges a campaign of strikes against electric power and other infrastructure, which Moscow suggests are aimed at reducing Kyiv's ability to fight and pushing it to negotiate.
