North Korea increased imports of vehicles and alcoholic beverages from Hong Kong in 2013, despite an overall drop in bilateral trade, a South Korean report showed Thursday. The trade representative office for Korea Trade-Investment Promotion Agency (KOTRA) in Hong Kong said Pyongyang spent US$4.36 million to buy vehicles, up 27.5 percent from the year before, a large number of them with over 3-liter engine and seating capacity for more than 10 people.
