North Korea has been silent on a UN Security Council resolution imposing sanctions on the communist country for its nuclear test declaration, a South Korean news agency said on Monday.
Shortly after the Security Council unanimously approved the resolution on Saturday, North Korea's chief UN envoy Pak Gil-Yon said his country "totally rejects" the resolution and will continue to take "physical countermeasures."
But the North's state-run Korean Central News Agency and two main broadcasters have not carried any reports or editorials denouncing the resolution, Yonhap news agency said.
Yonhap is the only South Korean news organisation allowed to monitor North Korean broadcasts.
North Korea for years has described sanctions as tantamount to a declaration of war.
"If the US increases pressures upon the DPRK, persistently doing harm to it, it will continue to take physical countermeasures, consider it as a declaration of war," a North Korean foreign ministry spokesman said last week.
Yonhap quoted an expert here as saying North Korea is expected to announce its official position soon through a statement from its foreign ministry or other related offices.
The Security Council, which imposed sanctions on the North following its July missile tests, broadened those measures in its new resolution demanding the elimination of all nuclear weapons, weapons of mass destruction and ballistic missiles.
It provides for inspection of cargo to and from North Korea, a travel ban on officials working on such programs, and a ban targeting missiles, tanks, large artillery systems, warships and combat aircraft.
