where is the main country of central america?

i fink its guatemala but im not sure

I think that is Panama.

Antigua and Barbuda, Dominica, Barbados, Bahamas, Granada, Jamaica, Santa Lúcia, Saint Kitts and Nevis, Saint Vincent and the Grenadines, Belize, Republic of Trinidad and Tobago, Cuba, Dominican Republic, El Salvador, Guatemala, Honduras, Nicaragua, Panama, Costa Rica, Haiti. Anguilla, Ilhas Cayman, Ilhas Turks and Caicos, British Virgin Islands and Montsserat. Holand Antilhas and Aruba, Guadeloupe and Martinique, American Virgin Islands.

But Panama has a strategic importance for the world, the existence of the channel changed the history of the world trade.

Is you are taking about the country with the better economy it is Costa Rica, it used to be Guatemala since it is the country with the best US relationship, but Costa Ricas economy has grown a lot in the last 3 years.

It would be Costa Rica if you want to see a country map here it is

There are six countries that make up Central America, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, and Panama. There is one that is the biggest, one that that has the best economy, one that has the best US relations, one that is farthest north, etc. etc. but there is no "main" country.
