July 4 (Reuters) - Ukrainian Black Sea and Danube ports' cargo shipments were 68% up in January-June compared with the same period last year, a senior lawmaker said on Thursday.

Six functioning ports processed 52.7 million tons of cargo compared with 31.3 million tons last year, he added.

Over 63% of total shipments constitute agricultural products. (Reporting by Yuliia Dysa; Editing by Andrew Heavens)
