The United States has listed India, China and Pakistan as major drug transit or source countries in its latest report on international drug trafficking. The designation identifies countries considered significant in the movement or production of illegal drugs, but it does not necessarily mean their governments are involved in drug trafficking or have failed to cooperate with the US. The report highlights the continuing challenge of controlling illegal drug production and cross-border trafficking. It also draws attention to the importance of international cooperation, stronger border checks, and coordinated action to tackle the global drug trade.
