North Korea says it will call a key parliamentary meeting next month to discuss amending the Constitution.

In January, North Korean leader Kim Jong Un gave a speech in which he called for the country's Constitution to be revised to define South Korea as the "No.1 hostile nation."

He also called for concepts such as "peaceful reunification" to be eliminated from it.

The Monday edition of the country's ruling Workers' Party newspaper Rodong Sinmun reported that it was decided to call upon regional delegates for the Supreme People's Assembly in the capital Pyongyang on October 7.

The paper said that the meeting will deliberate revisions to the Constitution, as well as trade with other countries and more.

The assembly is held once or twice a year to decide on matters including the national budget, legal amendments and personnel appointments to national organs. Its last meeting was held in January. It was there that Kim Jong Un called for the amendments.

The country subsequently revised a part of the lyrics of its national anthem by removing words representing the entire Korean Peninsula.
