Well obviously the South Korean and Japanese government and feigning anger at this recent test:

South Korea accused North Korea Tuesday of flouting a United Nations ban with its latest short-range missile tests, amid reports the communist state is planning more launches.

The North Monday launched five missiles off its east coast despite making a series of peace overtures since August.

Military experts said the launches could be part of routine exercises, but may also be a show of firepower for political purposes.

The North is under pressure to return to six-nation nuclear disarmament talks, which it quit in April.

The South’s Yonhap news agency said there were signs the North was preparing later Tuesday for more launches, this time off the west coast.

Japan’s coast guard said the North had warned of “firing exercises” day and night until October 25 in the Yellow Sea.  (…..)

Navy Chief of Staff Admiral Jung Ok-Keun told South Korean lawmakers the KN-02 missiles fired Monday have a range estimated between 130-160 kilometres (80-100 miles), greater than the 120 kilometres previously believed.

The foreign ministry said the launches breached UN Security Council resolutions banning ballistic missile tests, and urged the North not to repeat them.

Japanese Prime Minister Yukio Hatoyama told reporters in Tokyo that if the launch reports were correct, “I think it’s very regrettable.”  [AFP]

The KN-02 is based on the Soviet SS-21 short-range missile technology that is used at the tactical level, which North Korea received from Syria during the early 1990s. The North Koreans have tested this missile before so it isn’t like they are unveiling something new from their arsenal.  What is significant about this missile is that it flies a cruise missile profile that makes it difficult for PATRIOT missile batteries located in South Korea to intercept.  Also if you look at the range of the missile tested yesterday, if fired from around the DMZ area it could reach every US military installation on the peninsula all the way down to Camp Humphreys.   The missile also uses solid fuel which means no fueling of the missile is necessary before being launched.  This means that this system is very mobile and can be launched at a moments notice.  This is why the North Koreans have likely been conducting so many tests of this missile the past few years.

What I find interesting about this is that the South Korean and Japanese government are getting worked up over this missile test violating UN sanctions when it is small fries compared to the fact that the Chinese government just last week just signed a major economic package with the North Koreans in violation of UN sanctions and no one said a word.
