President Obama will have a meeting with Petro Poroshenko, Ukraine's new president-elect, during his trip to Europe next week. 

According to a top US official, Obama will meet with Poroshenko in Poland. 

"This is an important time for President Obama to affirm directly to President-elect Poroshenko our commitment to the people of Ukraine," deputy national security adviser Ben Rhodes said during a conference call Saturday. 

The Times of India reported that Obama will take a four-day trip to Europe, beginning with a celebration in Warsaw to mark Poland's 25th anniversary of their first elections following the fall of communism. Obama will then met with Poroshenko on Wednesday. 

"We have a broad agenda to work with them: to stabilize the economy, to provide significant assistance as they seek to re-establish stability and growth within Ukraine, and also, of course, to support their efforts to reduce tensions to pursue dialogue and unity within Ukraine, and also to work with the European allies, with Russia, and above all with the government of Ukraine to facilitate dialogue to reduce the tensions within Ukraine," Rhodes said. 

Rhodes said the United States is pleased that the Ukrainian people came out in large numbers to elect the new president. 

"We've admired his commitment to pursue dialogue and to aim to reduce tensions and put Ukraine on a positive path. In these days before his inauguration, this will be an important time for the president to check in directly and review his agenda," Rhodes said. 

He added that Poroshenko's election should be used as an opportunity for Ukraine and surrounding countries to reduce tension in the region, which has been plagued by violent protests for over two months. 

"We now have a clear mandate for President-elect Poroshenko. And this should be taken as an opportunity for all sides, both within Ukraine and in the surrounding neighborhoods, to work together to reduce tension," he said. 

He said that Russia has an opportunity to quell the violence, but the country has not yet taken steps to help their neighbor nation. 

"We believe Russia needs to use its influence on those separatists to calm tensions, to put an end to this violence and to engage in a dialogue with the newly elected government of Ukraine," Rhodes said. 

The United States and the European Union have said that they want to begin negotiations with the new Ukraine government to broker peace, and the same option is open to Russia. If Russia refuses to comply, it will most likely be hit with more U.S. sanctions. 

"Should they not take it, they will continue to face the isolation that they've been confronted with, the sanctions that have imposed a great cost already on their economy. So that's the choice that continues to be before the Russians," Rhodes said.
