Which is the highest growth country
your question seems to be incomplete but I am assuming that you are asking about the country with highest growth rate in economy.
With a projected 26.21% growth in 2020, Guyana is the fastest growing economy in the world. Guyana’s growth is expected to come in at:
12% in 2021
49% in 2022
28% in 2023
Guyana is a middle-income country and is covered by dense forests, and is home to fertile agricultural lands and abundant natural resources. Gold, bauxite, sugar, rice, timber, and shrimp are among its leading exports.
In 2000, the U.S. Geological Survey identified the Guyana-Suriname Basin as the second highest resource potential among unexplored oil basins in the world.
