US authorities are intending to issue additional funds to Kyiv, White House spokesman Josh Earnest has said.

"The scope of our financial assistance to Ukrainian authorities could increase significantly due to the unstable situation in the country provoked by Russia," he said at a press conference.

According to Earnest, "based on a number of reforms that they [the authorities of Ukraine] have carried out, we advocate the provision of financial assistance in the second half of this year," the White House representative said.

"We can and must do more to provide financial assistance to Ukraine," he added.

As reported, earlier President of Ukraine Petro Poroshenko thanked the United States for the issue of $2 billion in loan guarantees to Ukraine.
