Russia’s economy grew at the fastest pace in six years in 2018, outstripping economist estimates, as construction got a boost from the World Cup and the start of natural gas project in Siberia.

Growth accelerated to 2.3 percent, the most since 2012, after construction surged, the Federal Statistics Service reported in its first estimate Monday. The majority of analysts polled in a Bloomberg survey forecast growth of 1.9 percent for the year and the highest estimate was for 2.2 percent.
