ISLAMABAD - The Pakistan-China trade has constantly been affected due to submerged part of Karakoram Highway (KKH) as only 10 per cent trade has been possible on this shortest land route for the last 14 months, while the concerned authorities have been able to complete almost 15 per cent work only despite passing one year. Due to snail pace of work, the Frontier Works Organisation (FWO) has been able to perform around 15 per cent work, as it has to lower down the water level of Attaabad Lake till 36 kilometres but till now it could be able to perform work on only six kilometres, well-placed officials in the Communication Ministry shared with TheNation. Around a year before (January 2010) near Attaabad village in Hunza valley, due to massive landslides Hunza river was blocked and around 2-3 kilometre of road was submerged. If the work performed on this important project with this speed it could take around more six years that would ultimately badly damage trade between two friendly countries, said technical experts.
