State-run Beijing Automotive Industry Holding will take a stake in Koenigsegg as part of the Swedish luxury carmaker's purchase of General Motors' Saab unit, in the latest push by a Chinese auto firm to secure a global footprint.

BAIC will take a minority stake in Koenigsegg Group, which in turn is bidding to own 100 percent of Saab Automobile, Koenigsegg said in a statement on Wednesday.

The agreement comes just hours after another Chinese carmaker, Geely Automotive, said its parent wanted to bid for Saab's Swedish rival Volvo Cars Corp, which has been put up for sale by U.S. parent Ford.

This is an important step on the road toward a new Saab. We have a well prepared business plan, an important partnership and we are ready to proceed without state financing, Koenigsegg Chief Executive Christian von Koenigsegg said in the statement.

Koenigsegg, backed by U.S. and Norwegian investors, struck a deal earlier this year with GM to buy the Detroit automaker's loss-making Saab Automobile business, but questions remained regarding the financing of the deal.

BAIC dropped out of the bidding for Opel in July and had been tipped by some as a possible bidder for Ford-owned Volvo Cars.

The automaker, controlled by the Beijing government, aims to more than double its annual vehicle sales to 2 million units by the end of 2015 from 771,639 units in 2008.

However, BAIC does not even have its own car brand.

Its four-year-old Mercedes-Benz car venture with Daimler AG broke even last year and its tie-up with Hyundai Motor Co has a long way to go before catching up with top players in the market such as Volkswagen AG.

DEAL BY OCTOBER

Koenigsegg said it aimed to sign a finalised deal later this year and that the Swedish government, from which it hopes to secure state guarantees for loans from the European Investment Bank (EIB), had been briefed on the plans.

Further details regarding the deal could not be divulged due to a confidentiality agreement, it added.

We are now completely convinced that we will be able to complete the deal by the end of October, Saab spokesman Eric Geers said.

This naturally also offers fantastic opportunities for Saab in the Chinese market. It is clear that this will help Saab hugely.
