Barack Obama has warned the launch of long-range missile by North Korea harms the peace and stability of northeast Asia.Following talks with the EU in Prague the US president said: ‘‘I am very pleased with the joint statement with respect to the North Korean launch. I think it’s indicative of the fact that when Europe and the US act in concert we can make a difference not just on local issues but on international issues.’‘ EU chief Jose Manuel Barroso backed Obama’s calls for a collective response. ‘‘We want to work with the United states and with the international community. Namely, in the framework of the United Nations so we can have a common position.’‘ Describing North Korea’s move as ‘extremely regrettable’ Japan’s prime minister Taro Aso said: “They conducted the launch despite our repeated warning. We see this as an extremely provocative action that Japan cannot tolerate. We will continue to cooperate with the international community as this is a clear violation of the UN resolution.” The UN Security Council will hold an emergency session over the launch later today to consider what action to take.
