North Korea has blasted South Korea for imposing financial sanctions on seven foreign individuals and entities over their alleged arms trade with the communist country.

The Secretariat of the Committee for the Peaceful Reunification of Korea issued an "information bulletin" Saturday, accusing President Park Geun-hye's administration of heightening tensions on the Korean Peninsula.

"On June 26 the Park Geun Hye group blustered that it would opt for 'stronger pressure' to 'allure the north to change,' revealing independent 'financial sanctions on the north,'" the CPRK, Pyongyang's organ for handling inter-Korean affairs, said, according to an English dispatch carried by the North's Korean Central News Agency.

On Friday, Seoul announced sanctions on six Taiwanese individuals and entities and a Syrian research center, citing evidence of weapons trade with North Korea.

It was the first time Seoul imposed sanctions on foreigners and groups outside North Korea in a bid to put pressure on the nuclear-armed neighbor.

The CPRK also denounced the South over its recent plans to bolster its strike capabilities against the North.

"The DPRK will not pardon the provocative moves of the Park group deliberately foiling the inter-Korean relations and inciting a war fever in order to attain its despicable political purpose but sternly punish it in the name of the entire nation," the report said. DPRK is the acronym of North Korea's official name, the Democratic People's Republic of Korea.

"Provokers will face merciless punishment and miserable ruin." (Yonhap)
