Kuwait's telecom giant Zain group has denied reports that it has received new offers for the purchase of its operations in 15 African nations.

"The group would like to inform (the bourse) that there are no new offers at present," for the purchase of its African assets, Zain said in a statement posted on the Kuwait Stock Exchange website.

Shares of the largest listed firm in Kuwait rose by more than 10 per cent in the past two days over the reports, and its market capitalisation gained about $1.6 billion to $14.6 billion, according to a report in our sister newspaper Gulf Daily News.

Zain entered the African market in 2005 by buying the Dutch Celtel operations for $3.5 billion. Later, it made bold acquisitions in Nigeria, Sudan and other smaller nations.

Last year, Zain entered into serious negotiations with a number of bidders, including French telecom group Vivendi, for the sale of its African assets, but the talks faltered because the bids were below expectations. In September, major shareholders Al Khorafi Group signed an initial agreement to sell a 46 per cent stake worth $14 billion to an Indo-Malaysian consortium that included two state-owned Indian telecom firms.

The deal was supposed to have been completed in four months. The deadline has passed without any progress, but the investors still stressed that the deal is not dead, although it will take more time.
