The North test-launched a new type of its cruise anti-ship missiles on Thursday, its fourth missile test since the South's Moon took office on May 10, pledging to engage in dialogue with Pyongyang. Song, who served in the navy for more than three decades, was Moon's main security adviser during his presidential campaign, reprising his role in Moon's 2012 presidential campaign. A decorated veteran, Song took part in a 2009 skirmish between North and South Korean naval vessels off the western coast of the Korean peninsula. Song's appointment does not need parliament's approval, but he must attend a hearing and answer questions from lawmakers. The Blue House said Song admitted to having falsely registered his residence information in the past, a criminal offense in South Korea. Many of Moon's ministerial choices have faced an uphill battle in parliament on this and other ethical issues, and lawmakers are likely to grill Song the same way. He is expected to cooperate with the United States, the country's major military ally, to respond to the North's growing missile threat. The government has said it will not change a pact with the United States for the deployment of a U.S. anti-missile system in South Korea, despite its decision to put on hold the full installation pending an environmental impact review. Moon also tapped a human rights expert as justice minister tasked with reforming the prosecutors' office, the president's office said.
