A technical assistance (TA) mission on external sector statistics (ESS) was conducted for the Central Bank of Myanmar (CBM) in Nay Pyi Taw during June 3–5, 2019, as part of the Project on the Improvement of ESS in the Asia–Pacific region. The Project is funded by the Government of Japan; managed by the IMF’s Statistics Department (STA); and implemented by the IMF Capacity Development Office in Thailand (CDOT). The work on verifying reasonable size of coverage adjustments for Myanmar’s imports was addressed during the mission, using bilateral trade data from Thailand and China. Under conservative scenario (i.e., excluding trade through land border check points which potentially involves exports from Thailand and China going through Myanmar onward to the final destination countries), the analysis suggested that Myanmar’s 2018 imports are under-reported by approximately 1.9 billion USD for Myanmar’s imports from Thailand (total discrepancies are 2.0 billion USD), and another 1.9 billion USD for Myanmar’s imports from China (total discrepancies are 4.3 billion USD).1
