BRUSSELS, May 27 (Xinhua) -- Leaders of the European Union (EU) countries on Tuesday called on all parties to accept the outcome of Ukraine's presidential election held on Sunday.
"We expect the Russian Federation to cooperate with the newly elected and legitimate president, to continue the withdrawal of armed forces from the Ukrainian border and to use its leverage on the armed separatists to de-escalate the situation in Eastern Ukraine," said a statement issued after an informal dinner of heads of state or government of the EU.
The European leaders said Russia should, "as a matter of priority," prevent the crossing of separatists and weapons into Ukraine, adding "in this context and with a view to consolidating a political solution, we encourage the Russian Federation to enter into a frank and open dialogue."
The statement urged the Ukrainian authorities, building on the legitimacy of the newly elected president, to continue to reach out to the population and civil society of all regions of Ukraine, including in the framework of the round-tables of national dialogue.
The statement added that a swift and inclusive conduct of the constitutional and de-centralization reforms, while drawing on the relevant expertise of the Council of Europe, "is key in this process."
Ukrainian businessman and presidential candidate Petro Poroshenko won Sunday's election with 53.72 percent of the vote, followed by ex-prime minister Yulia Tymoshenko with 13.09 percent and Oleh Lyashko, 8.47 percent, according to the country's Central Electoral Commission.
On Monday, Russia said it will respect the will of Ukrainians in their presidential election, but warned Kiev against resuming a military operation in the country's southeastern regions.
Foreign Minister Sergei Lavrov told reporters that Moscow is ready for dialogue with Poroshenko, but it "definitely does not need" mediators in talks with Kiev.
