KYIV, Dec 30 - Secretary of the National Security and Defense Council Oleksiy Danilov believes that Ukraine's positions in the international arbitration for $4.5 billion initiated by the Chinese buyers of Motor Sich shares are strong.

"I emphasize once again that we are not particularly worried about this here," he said at a briefing in Kyiv following the NSDC meeting.

Danilov explained his position by having an understanding of "what were the investments that they (the buyers) refer to" and what China has to do with this.
