Difference between claim and agreement in Korean
주장·동의

주장claim
"Claim" means saying that something is true, right, or real. The Korean word 주장 can also mean a strong opinion that someone says firmly. You often use it when people disagree and one person says, "This is true" or "I am right."

동의agreement
동의 means agreement or saying that you agree with something. You use it when you think an idea, plan, or choice is okay. In daily conversation, people often say 동의해요 to mean “I agree.”
The difference
주장 is what someone says or insists is true. 동의 is agreeing with that opinion or idea.
