North Korea says it has made partial revisions to its constitution, although it remains unclear whether the changes include designating South Korea as the "No.1 hostile country."

Wednesday's edition of the Rodong Sinmun, the ruling Workers' Party newspaper, reported that the 14th Supreme People's Assembly took place in Pyongyang from Monday to Tuesday, with representatives from various regions attending.

It says the assembly adopted amendments and supplements to parts of the constitution as well as legislation related to light industry and foreign trade.

The report did not mention whether North Korean leader Kim Jong Un attended the gathering.

At the previous assembly in January, Kim had ordered revisions to the constitution to define South Korea as the "No.1 hostile country" and called for the removal of expressions such as "peaceful unification." Pyongyang has yet to disclose whether these changes have been made.

South Korea's Yonhap News Agency suggested that North Korea may have indeed made those changes but has chosen not to publicize them.

But some South Korean experts say the timing of the amendments may have been postponed in consideration of the US presidential election in November.
