The exercises would begin in December, according to South Korea's Yonhap News Agency.
The statement, which called the country's nuclear program "righteous and inevitable", continued: "He boasted about the "overwhelming superiority of USA power" and 'peace through strength.'

"Multiple carrier strike force operations are very complex, and this exercise in the Western Pacific is a strong testament to the US Pacific Fleet's unique ability and ironclad commitment to the continued security and stability of the region", Adm. Scott Swift, the commander of the US Pacific Fleet, said in a statement.
Trump will fly to Manilla on Sunday afternoon for the Association of Southeast Asian Nations (ASEAN) meetings and East Asia Summit, which will both be comprised of leaders from Southeast Asian nations and representatives from dialogue countries.
"The weapons you are acquiring are not making you safer", Trump added.
"They are putting your regime in grave danger". That includes a stern speech delivered in South Korea's National Assembly on Tuesday, in which he said: "Do not underestimate us".
But Pyongyang doesn't seem interested in negotating.
President Trump responded to the latest round of name-calling from North Korean leader Kim Jong Un on Saturday, saying "I try so hard to be his friend" and would "never call him "short and fat". "Trump, during his visit, laid bare his true nature as destroyer of the world peace and stability and begged for a nuclear war on the Korean peninsula", a North Korean official said in a statement on Saturday.
It's odd, one minute Kim is talking about nuclear war, testing missiles, then he calls Trump "old".
Tensions between North Korea and the USA have escalated in recent months following the rogue state's sixth nuclear bomb test on September 3, which earned more sanctions and condemnations from the UN.
