"중국은 대통령이 없습니다."
Translation:China does not have a president.
That's not the point. Word 대통령 means 'president', but it is usualy used when refering to the presidents of capitalist countries. 국가주석 also means 'president', but of a socialist country, like China.
김일성 국가주석 - president Kim Il Sung; 시진핑 국가주석 - president Xi Jinping; 챠우쉐스꾸 국가주석 - president Ceaușescu
트럼프 대통령 - president Trump; 문재인 대통령 - president Moon Jae-in
"There is no president in China" would be a correct alternative. Posted on Jan. 2, 2018.
