SEOUL: North Korea has deleted allreferences to uniting with South Korea from its constitution, a document reviewed on Wednesday showed, underscoringPyongyang`s push for a more hostile policy towards Seoul.

North and South Korea remain technically at war because their 1950-53 war ended in an armistice, not a peace treaty.

Pyongyang`s constitution had previously contained a clause stating that it aimed `to realise the unification of the motherland`.

That reference no longer appears in the latest version, presented on Wednesday by a professorduring a news conference at South Korea`s Unification Ministry.

North Korean officials considered constitutional amendments at a major congress in March, where leader Kim Jong Un labelled Seoul as the `most hostile state`.

The deleted clause used to say that the nucleararmed nation would struggle for `national reunification on the principles of independence, peaceful reunification, and great national unity`.

The revised constitution, which the document indicated was introduced in March, also includes a new clause delineating North Korea`s territory.-AFP
