The point is not about whether a country imports at all, but whether it can mobilize domestic production of essential food crops in times of crisis.
Even China import and has rice reserves. There is a reason these government have and subsidized rice reserves rather tea reserves.
To put it crudely Japan doesn't need to grow all its own food because people send it money for Toyotas and Mitsubishi cargo trucks and such, and it uses that to buy whatever food it wants.
Sri Lanka could, but not with the chemical fertiliser ban.
