This report assesses the quality of Lao PDR’s trade statistics by comparing Lao PDR’s export/import data with its trade partners’ import/export data (mirror data). While the mirror technique is constrained by the fact that partners’ data also can have some problems, it is a useful method to obtain a snapshot of the quality of trade data. First of all, it should be recognized that publicly available Lao PDR statistics compiled by the Ministry of Industry and Commerce (MIC) is not consistent with the Harmonized System (HS) classification. It is advisable that Lao PDR should release the HS classification-based trade data compiled by the Ministry of Finance. The overall quality of Lao PDR’s export data is relatively good compared with its import data. Most differences between Lao PDR’s and trade partners’ trade statistics can be explained by mineral-related and wood-related products. While the exports of minerals and wood-related products are supposed to be effectively managed by the Lao government, there is a possibility that some of those products are exported to neighboring countries outside the control of the Lao government.
