Foreign Secretary Philip Hammond said today's meeting with his EU counterparts was "an opportunity to send a very clear signal to Russia" over the downing of flight MH17.
Speaking as he entered the Brussels meeting, Mr Hammond said: "We're obviously pleased that there is movement now on repatriating victims, pleased that there is some access being granted to the site.
"But we mustn't forget the overall context - this terrible incident happened in the first place because of Russia's support to the separatists in eastern Ukraine, because of the flow of heavy weapons from Russia into eastern Ukraine, and we have to address that issue today."
"I shall be urging my colleagues and our partners to send a very clear and strong signal to Russia today," the Foreign Secretary added.
Thousands of online users have taken to social media to call for the victims of the Malaysian airliner crash to be returned to loved ones.
United States intelligence officials admitted that they do not know who fired the surface-to-air missile that downed flight MH17.
