Ukrainian President Petro Poroshenko is expected to visit Singapore and Australia next week, a source familiar with the Ukrainian leader's plans told Interfax.

"The head of state will visit Singapore on December 9-10, and Australia on December 11-12," the source said.

The agenda for Poroshenko's visit will include assistance for Ukraine's key reforms, the prospects for military-technological cooperation, as well as ways to speed up the investigation into the July 17 Malaysia Airlines Flight MH17 crash in southeastern Ukraine.
