Asian stocks gained on Monday, after Europe took a step towards fiscal union, and news China is planning to invest in Europe. Shares outside Japan rose 1.2 percent, after sliding 3.5 percent last week, but the euro fell, amid concern over the adequacy of the euro zone's latest safety net. Daiwa Capital Markets' Sun Mingchun says many questions remain. (SOUNDBITE) (English) DAIWA CAPITAL MARKETS, HEAD OF CHINA RESEARCH & CHIEF ECONOMIST FOR ASIA EX-JAPAN, MINGCHUN SUN, SAYING: "The solution from the EU summit to me is still a temporary solution. A lot of things have not really been answered, especially about the competitiveness of these economies in trouble. And also the ECB has not agreed to buy Eurobonds in the future." Still, the agreement to pursue stricter euro zone budget rules, steps to provide up to 200 billion euros in funding, and a report that China plans a new $300 billion vehicle to invest in Europe, lifted investor sentiment. Japan's benchmark Nikkei 225 rose over one-and-a-half percent, with blue chip exporters leading gains. Even Toyota rose as investors welcomed the certainty from its lowered profit guidance. Market heavyweight Samsung Electronics added over 2.5 percent, after the South Korean technology firm said it sold more than 300 million mobile phones this year. In Hong Kong, financial stocks led the gainers, but stocks in Shanghai slipped after China's exports came in at their slowest in nearly two years, with the festering debt crisis in Europe, shaving demand from its single largest trading partner.
