LONDON- Ukraine's economy is likely to shrink by 5% in 2020, slightly more than the 4.8% contraction forecast earlier in the year, economy minister Ihor Petrashko said on Monday.

Most sectors of economic activity showed improvement in October and economic growth will rebound by 4.6% in 2021, he told participants in a Ukraine investment roadshow.
