The term refers to the final city or harbor from which a traveler or goods depart en route to Cambodia. This denotes the immediate prior location of departure before entering Cambodian territory. For example, if an individual traveled from Singapore to Phnom Penh, Singapore would be considered the last city/port of embarkation before Cambodia. This is regardless of any prior stops or origin points earlier in the journey.
Knowing the last point of origin before entering Cambodia is crucial for immigration, customs, and trade purposes. It aids in tracking travel routes, identifying potential sources of goods, and verifying the origin of individuals or shipments. Historically, this information has been vital in controlling the spread of diseases, preventing illegal immigration, and regulating commerce entering the country. Maintaining an accurate record contributes significantly to border security and the efficient management of cross-border movements.
