* Geely to increase stake in Saxo Bank to 51.5 pct from 30 pct
* Carmaker will pay more than $300 mln for the additional shares
* Deal is part of Beijing's swoop on European financial assets (Updates to specify deal price)
COPENHAGEN, Oct 2 (Reuters) - Chinese carmaker Zhejiang Geely Holding Group will increase its stake in Denmark's Saxo Bank to more than 50 percent in a deal that highlights China's drive to tap the expertise of European financial firms.
Beijing has generally been trying to slow the pace of overseas investments by Chinese companies, worried about capital outflows. But there are signs the authorities are still supportive of investments in foreign financial firms, particularly to access new technologies.
Last month Legend Holdings, which owns computer maker Lenovo, bought Banque Internationale a Luxembourg (BIL) for 1.48 billion euros ($1.76 billion).
Also last month sources familiar with the matter said that two of Chinas most acquisitive conglomerates, HNA Group and Anbang Insurance Group, had separately considered bidding for German insurer Allianz SE.
Geely said in May that it would take a 30 percent stake in Saxo bank as part of a diversification drive. The deal, which is still awaiting regulatory approval, is the first major investment into financial services for the Chinese company that owns Swedish carmaker Volvo.
Now Geely aims to lift its stake to 51.5 percent at a cost of $300 million for the additional 21.5 percent. Geely's planned 51.5 percent stake will cost the company a total of more than 800 million dollars.
Despite its name, Saxo Bank derives most of its income from its online trading platforms for private foreign exchange traders and others rather than traditional banking.
"Saxo Bank is an attractive investment for Geely because the bank, as a FinTech (financial technology) and RegTech (regulatory technology) company, has always had its main focus on technology," a Geely spokesman said in an email to Reuters.
He said Geely believed that Saxo Bank's technologies and product value could be expanded across Asia.
Finland's Sampo Oyj also said on Monday that it would buy a 19.9 percent stake in Saxo Bank for 265 million euros.
A spokesman for Saxo Bank told Reuters that Geely would buy its shares under the same terms as Sampo. Geely's spokesman said the Chinese company would not comment on the price paid.
Current Saxo Bank shareholders TPG Capital and SinarMas have accepted the offers from Geely and Sampo and will sell their stakes of 29.26 percent and 9.9 percent respectively, Saxo said.
Saxo's chief executive Kim Fournais, who founded the company with Lars Seier Christensen and Marc Hauschildt in 1992, will keep his 25.71 percent stake. Christensen agreed in May to sell his shares to Geely.
Saxo Bank has 1,600 employees in 18 countries and made operating revenue of 2.9 billion Danish crowns ($457.46 million) last year. Geely has more than 60,000 employees worldwide.
