Germany's Chancellor Angela Merkel will be raising the issue involving Russia's aggression against Ukraine in the seawaters of the Black Sea close to the entry into the Kerch Strait and request a response to it at the 2018 G20 Buenos Aires summit, Ukraine's Prime Minister Volodymyr Hroysman has said.

"I think this topic will be thoroughly discussed at the G20 summit. We have just finished our meeting with Ms. Federal Chancellor of Germany and she is about to leave for the G20 meeting to discuss, in particular, Ukrainian issue there," Groysman told reporters in Berlin on November 29 following his talks with Merkel.

He said the first issue that was discussed during their meeting was "the situation in the Azov Sea and the fact that a naked aggression by Russia took place there against our naval seamen." "We have also discussed measures that need to be taken to get our prisoners of war released," the prime minister said.

"We discussed the ongoing situation in the Sea of Azov. And I want to say that the federal chancellor is very well informed about the situation and all the aspects of what happened and which problems have been created there today by Russia, including the illegitimate construction of that bridge, troubled navigation, and so forth," Groysman said, adding that "it cannot be left without a proper reaction from the world to all those outrages."
