* Market helped by foreign buying after BOJ moves -analysts
* MMC and Peugeot in talks that could mean capital tie-up
By Aiko Hayashi
TOKYO, Dec 3 (Reuters) - Japan's Nikkei average climbed more than 3 percent to hit a three-week high on Thursday as exporters such as Canon Inc <7751.T> jumped on a weaker yen, while metals shares climbed after gold hit a new record.
Mitsubishi Motors Corp <7211.T> soared nearly 20 percent after the Nikkei business daily reported that PSA Peugeot Citroen <PEUP.PA> is in talks to spend up to 300 billion yen ($3.4 billion) to acquire a 30-50 percent stake. [
]Mitsubishi Motors and Peugeot confirmed they were discussing an expansion of their existing partnership that could end in a capital tie-up, underscoring the intensifying pressure to consolidate in the fiercely competitive auto industry.
Stocks of Mitsubishi Motors shareholders, such as trading house Mitsubishi Corp <8058.T>, also climbed.
Market players said the overall market likely received a boost from buying by foreign investors partly because they took heart from recent moves by the government and the Bank of Japan on the economy.
"Foreign investors are likely putting their money into the Japanese market as the least risky place after Dubai's debt problems revived worries about risk-taking and also after the BOJ unveiled financial measures," said Hajime Nakajima, deputy general manager at Cosmo Securities.
"But they are not really buying due to Japan's bright economic prospects ... The market is also in a position to attract foreign money this month after a decline in the weighting of Japanese stocks in global allocations of their portfolios."
The benchmark Nikkei <
> jumped 3.4 percent to 9,933.81, its highest level since Nov. 12 and well above its 25-day moving average around 9,700.The broader Topix <
> gained 3.1 percent to 885.15.The BOJ said on Tuesday it would offer around 10 trillion yen ($114 billion) in three-month funds at 0.1 percent and keep its key interest rate steady at 0.1 percent.
The central bank had surprised investors by calling an emergency policy meeting in the face of government pressure to do more to beat deflation. [
]The yen extended its losses against the dollar on growing investor speculation that Japan may take more quantitative easing steps to get the economy out of deflation and on prospects for potential currency intervention. [
]The dollar gained 0.5 percent to 87.77 yen <JPY=>. Investors fret about a stronger yen since it eats into exporter profits when repatriated.
"The yen's fall against the dollar has set off short-covering," said Takashi Ushio, head of the investment strategy division at Marusan Securities.
"The Nikkei was oversold last week and so it was primed for a rebound, and there are also hints that perhaps foreign buying may be starting to pick up as well."
Finance Ministry data showed foreign investors bought a net 61.5 billion yen ($703 million) of Japanese stocks last week, and orders placed through foreign securities houses in Tokyo showed foreign brokers were set to be net buyers on Thursday.
