Why is Eswatini considered a landlocked country?

Eswatini is considered a landlocked country because it is an independent sovereign state that lacks direct access to an ocean or a sea that is not landlocked.1

Geographically, Eswatini is situated on the eastern flank of South Africa and shares its borders with South Africa and Mozambique. Being entirely surrounded by these land territories, it does not possess a coastline. While the country is well-watered by several perennial rivers that flow through its territory toward the Indian Ocean, these waterways do not provide the nation with direct maritime access.2345
