The People's Liberation Army Navy commences artillery exercises in the Yellow Sea in response to those being conducted by South Korea and the United States against North Korea.
According to South Korea's Yonhap news agency, North Korea appears to be preparing a test-launch of an intermediate-range ballistic missile. This comes after what the United States described as the "fiery, catastrophic" failure of the first attempt a few days prior.
The President of South Korea, Lee Myung-bak, gives an address to a joint session of the United States Congress, emphasizing the importance of a recently-concluded free trade deal between South Korea and the United States, and expounding the need to improve relations with North Korea.
South Korea and the United States cancel a joint naval drill against North Korea in the Yellow Sea, citing its previous anti-submarine training -- held from Sept. 27 to Oct. 1 -- and a desire "not to irritate neighboring countries" ahead of the upcoming 2010 G-20 Seoul summit.
North Korea responds to nearby joint United States-South Korean military exercises by stating that the acts resemble 19th century "gunboat diplomacy", describing them as "a threat to the Korean peninsula and the region of Asia as a whole".
