When a country is too small to affect the world price allowing for free trade will never increase total surplus?

When a country is too small to influence world prices, it is considered a price taker in international markets. In this scenario, allowing free trade will not increase total surplus because the country can access goods at the same prices as before trade, ensuring that domestic consumers and producers are unaffected by international price shifts. Consequently, the total surplus remains unchanged as there are no gains from trade, making free trade ineffective in enhancing overall economic welfare for such small countries.
