The CBS sitcom has previously come under fire for its portrayal of foreign characters, including Moy's Han Lee - a restaurant boss who speaks in broken English.
"I know that a lot of people had concerns about Han and the accent," Moy told the Los Angeles Times. "But the comedy on 2 Broke Girls always comes from a place of love - it's never mean.
"We're a comedy, and we often go right to the edge. It doesn't bother me. I've encountered this all my life. I've been made fun of all my life."
The actor - who is of Chinese descent - argued that the Korean accent he uses on the show is more suitable for television than a more realistic mode of speech, which "would be more incomprehensible and unintelligible".
"There's a lot of Han in me," he continued. "If you take out the accent and the naïveté, I'm a lot more realistic."

Moy concluded by suggesting that the character of Han has evolved since 2 Broke Girls debuted and is now "more of an individual than a type".
"When a sitcom is lucky enough to get a chance to grow, every character goes past the original surface level," he said.
2 Broke Girls airs on CBS in the US and on E4 in the UK.
