My comment:
(a) Paragraph 3 is: "防卫省最近没宣布日本自卫队正在东南亚和美国加州举行的联合军演，目前日本、美国、泰国、印尼等七国正在泰国清迈展开最大规模东南亚联合军演。"
My opinion is that the comma at the end of teh first 联合军演 should be a period ("。").
(b) Teddy Ng, Japan Accuses Beijing of Sending Surveillance Vessels to Diaoyus; Four Chinese ships seen by Japan's coastguard in disputed waters on Sunday for first time since last week's fire-control radar incident. South China Morning Post (SCMP), Feb 12, 2013. http://www.scmp.com/news/china/a ... nce-vessels-diaoyus
("Beijing sent maritime surveillance vessels to patrol waters near disputed islands in the East China Sea on Sunday and yesterday, the first two days of the Lunar New Year")
The second (and last) part of the SCMP report talks about the "Iron Fist" drill (Jan 15-Feb 22, 2013; at San Clemente Island, Caifornia) is "the largest joint drills conducted in the US since 2006, with 1,000 US troops and 280 Japanese troops taking part."
(i) San Clemente Island http://en.wikipedia.org/wiki/San_Clemente_Island
(owned and operated by the United States Navy; part of Los Angeles County; The city of San Clemente in Orange County, California is named after the island)
Quote: "The first European to sight the island was Juan Rodríguez Cabrillo in 1542, who named it Victoria. It was renamed by Spanish explorer Sebastian Vizcaino, who spotted it on November 23, 1602, Saint Clement's feast day.
