North Korea's Attack on South Korean War Ship

South Korea is showing signs of trying to cool tensions with North Korea, despite the international conclusion that a North Korean torpedo sunk a South Korean ship last month, leaving 46 sailors dead or missing. One of many unanswered questions is why China has had so little to say. China was quick to condemn the Israeli attack on the aid ships, saying it was "shocked" and "appalled," and demanding "a quick response" from the UN Security Council.  We have updates from Seoul, the UN and Washington.
