The United States condemned the launch as “provocative” and a breach of U.N. rules, while Japan’s U.N. envoy called for a Security Council meeting. However, diplomats say further tough sanctions are unlikely from the Security Council as China, the North’s only major ally, will oppose them.

“The international community must work in a concerted fashion to send North Korea a clear message that its violations of United Nations Security Council resolutions have consequences,” the White House said in a statement.

U.S intelligence has linked North Korea with missile shipments to Iran. Newspapers in Japan and South Korea have reported that Iranian observers were in the North for the launch, something Iran has denied.

Japan’s likely next prime minister, Shinzo Abe, who is leading in opinion polls ahead of an election on Sunday and who is known as a hawk on North Korea, called on the United Nations to adopt a resolution “strongly criticising” Pyongyang.

A North Korean Foreign Ministry spokesman reiterated that the rocket was a “peaceful project”.

“The attempt to see our satellite launch as a long-range missile launch for military purposes comes from hostile perception that tries to designate us a cause for security tension,” KCNA cited the spokesman as saying.

“STUMBLING BLOCK”

China had expressed “deep concern” prior to the launch which was announced a day after a top politburo member, representing new Chinese leader Xi Jinping, met Kim Jong-un in Pyongyang.

On Wednesday, its tone was measured, regretting the launch but calling for restraint on any counter-measures, in line with a policy of effectively vetoing tougher sanctions.
