Thai firm Kindest Place Groups Limited has offered a higher price to acquire Fraser and Neave's 7. 3 percent direct interest in Asia Pacific Breweries (APB), the maker of Tiger beer, Fraser and Neave (F&N) said on Tuesday.

With the unsolicited bid, Kindest Place is offering a price of 55 Singapore dollars per share for the APB stake.

The board of F&N has previously agreed to accept an offer from Heineken for its direct and indirect stake, totaling 40 percent, at 50 Singapore dollars a share. The deal was worth a total of 5.1 billion Singapore dollars (4.1 billion U.S. dollars).

F&N has until 5:00 p.m. on Aug. 16 to respond to the offer.

F&N said its board will "review and evaluate the offer" made by Kindest Place, which is linked to Thai billionaire Charoen Sirivadhanabhakdi, who owns Thailand's largest brewer, Thai Beverage.

Kindest Place has recently been increasing its stake in APB on the stock market as Heineken made the offer. Should the deal go through, the stake of Kindest Place in APB will rise to 15.9 percent.

Thai Beverage currently owns about 24 percent stake in F&N, while Kindest Place owns 8.6 percent in APB.

Local broadcaster Channel NewsAsia quoted a spokesman of Heineken as saying that the offer made by Kindest Place is not comparable to the Heineken offer, which is for F&N's total 39.7 percent effective stake, both direct and indirect, in APB and some other assets in a deal worth 5.3 billion Singapore dollars.
