SEOUL, June 29 (Reuters) - Shares in South Korea's Daewoo Engineering & Construction Co (047040.KS) jumped 15 percent on Monday after its cash-strapped controlling shareholder, Kumho Asiana Group, said it was looking to sell its stake.

Kumho Asiana said in a statement on Sunday that it plans to consider a tender offer, or a sale of its stake to a planned private equity fund set up by state-run Korea Development Bank

Kumho holds about 33 percent of Daewoo, while financial investors linked to the group, hold a further 39 percent. Their combined ownership is worth 3.4 trillion won ($2.6 billion) at the current market price.

"One of the main factors that had been pressuring Daewoo Engineering stock was that Kumho Asiana Group has management rights over the company," said Cho Joo-hyoung, an analyst at Hana Daetoo Securities.

"There have been worries about Kumho Asiana Group's financial health for quite some time.... and concerns that Daewoo Engineering may have to share the burdens weighed. The news eases such worries," Cho added.

Daewoo Engineering shares rose by their 15 percent daily limit to hit a nine-month high and were up 9.3 percent at 14,100 won at 0450 GMT, outperforming the wider market's 0.5 percent fall.

Shares in Kumho Asiana companies edged higher, with analysts saying a sale of Daewoo Engineering would mitigate some of the group's liquidity issues but would not help its earnings.

Petrochemicals-to-airline conglomerate Kumho Asiana bought Daewoo Engineering, South Korea's third-largest construction company, for about 6.4 trillion won ($5 billion) in 2006 as part of a debt-fuelled acquisition binge.

The country's 13th-largest business group by assets was among a handful of medium-sized conglomerates which over the past few years made aggressive leveraged buy-outs in their drive to grow closer in size to top-tier groups such as Samsung and LG.

Concerns about Kumho Asiana's financial problems deepened after it delayed its announced plans to raise 4.55 trillion won by selling assets, including unlisted Kumho Life.
