The transportation and electricity sectors will continue to serve as major powerhouses to fuel international infrastructure development in Belt and Road economies, according to a report released on Thursday.

As shown by indicators between 2007 and 2016, the two sectors registered faster growth than the overall infrastructure industry, and became dominant driving forces of infrastructure development, said the report by the China International Contractors Association.

CICA Chairman Fang Qiuchen said: "Infrastructure potential in markets related to the Belt and Road Initiative is enormous, and will keep growing in the future. Transportation and electricity facilities are projected to maintain a fast growth pace."
