Formerly friendly relations between the two countries soured in the wake of an investigation into the murder in Kuala Lumpur last month of Kim Jong Nam, the estranged half-brother of North Korea's leader, Kim Jong Un.
"We will have to release the body eventually either to the (North Korean) government or the next of kin", the minister said.
Washington and Seoul assure the drills are purely defensive, but North Korea rages against them and threatens all out-war.
Kim also said USA and South Korean assertions the assailants were unaffected while applying VX to a victim was an "absurdity".
Malaysian police on Friday formally identified Kim Jong Nam as the victim of a fatal nerve agent attack at Kuala Lumpur's airport, an expected but significant development in a case that has broken down the once-warm ties between North Korea and Malaysia.
However sources close to the matter said Japan provided Malaysia with Kim's fingerprints, obtained from when the Japanese government detained him back in 2001 at Narita global airport for trying to enter the country on a false passport.
Furthermore, 801 North Koreans have been given temporary working visas and about 180 of them work as miners in Sarawak, he disclosed, adding that records showed there are only 312 North Koreans in Malaysia as the others have returned to their country.

Maintaining peace between the groups in Manbij will be crucial if they will work together in the battle for Raqqa. They are preparing to move in to assault the city of Raqqa, IS's self-declared capital, according to reports.
According to Malaysian police, Kim was allegedly killed by two female assassins who smeared the highly toxic VX nerve agent on his face while he was waiting to board a flight to Macau on 13 February.
Malaysian authorities say the two women who allegedly poisoned Kim were recruited by a team of North Koreans.
They have also requested the match be moved to a neutral venue on safety grounds, with the North Korean regime now banning Malaysians from leaving the country.
North Koreans related to trade and other businesses said they were notified of the order by secret police officers and State Security Ministry officials on Saturday morning. Jong Nam died within 20 minutes of the attack.
Geneva -North Korea on Monday boycotted a special session at the UN Human Rights Council, where experts warned that the country's increasing isolation could worsen its already disastrous rights situation.
Jong Nam's son, Kim Han Sol, 21, last week appeared in a video to say he's gone into hiding with his mother and sister.
