China National Petroleum Corp ceased sales of diesel and gasoline to North Korea over the past several months, according to a report last month, and it is taking its toll at the gas pump, Rueters reports this week.

As of July 5, gasoline prices had surged to US$2.18 per kg (oil products are sold by weight in N Korea), up 50% from US$1.46 per kg on June 21, according to Reuters analysis of data collected by the Daily NK website.

By July 12, prices had eased to US$2.05 per kg, still more than twice the level seen at the start of the year, when prices were averaging under US$1 per kg.
