KYIV, Feb 17 – A group of Chinese investors updated their lawsuit against Ukraine to seek $3.6 billion in damages, up from $3.5 billion, after the authorities have blocked a hostile takeover of aerospace firm Motor Sich.

"The increase in the amount of the previous claims is due to the fact that the initial group of plaintiffs was expanded to include several more Chinese shareholders, who also suffered significant losses due to Ukraine's actions in violation of its international obligations," the plaintiffs said.
