Ukraine aims to conclude negotiations to revise its investment treaty with Japan by year-end to add momentum for economic recovery, a senior Ukrainian government official said Wednesday.

"It's an ambitious goal to make it by the end of this year," Yuliia Svyrydenko, first deputy prime minister and minister of economy, said in an interview with Jiji Press.

Expressing gratitude for Japan's support for war-torn Ukraine, she stressed her determination to conclude the negotiations at an early date so as to promote private investment.
