The Korea Open kicked off Tuesday in the country's central city of Daejeon, about 160km south of the capital Seoul. It would last till Sunday.

It brought together some 230 players from 27 countries, including the DPRK which joined the South Korea-hosted table tennis event for the first time.

Suh is South Korea's top-ranked female player, listed as No. 13 on the world rankings, while Kim is the 2016 Olympic bronze medalist in singles, who is ranked No. 55.

"This Korea Open is our first doubles. Our first goal was to pass the qualification stage. Now, we want to progress step by step," said the South Korean player.
