Asian shares declined Monday amid disappointment over corporate developments, including those related to false fuel-economy claims by South Korea's Hyundai and Kia and speculation over the future of Japan's beleaguered Sharp. Overall, investors remain wary of recent gains in the markets, and "I don't see there being significant change until the political situation stabilizes in China and the U.S., and Europe is still a worry," commented Benjamin Tam of IG Investment in Hong Kong. The Nikkei lost 0.48% to 9,007.44, the Hang Seng was down 0.47% at 22,006.40, the Kospi declined 0.55% to 1,908.22, and the S&P/ASX was up 0.37% to 4,474.10.
