Hanwha Group said on Monday that it has signed a tentative agreement with Daewoo Shipbuilding and Marine Engineering(DSME) to invest two trillion won in return for a 49 percent stake in the shipbuilder.

The country's seventh largest conglomerate said that it also signed an agreement with the state-run Korea Development Bank(KDB), DSME's biggest shareholder, on cooperation for normalizing the shipbuilder. 

The KDB currently owns a 55-point-68 percent stake in the shipbuilder. If Hanwha is selected as the final bidder, it will hold a 49-point-three percent stake in DSME, while the KDB will see its stake shrink to 28-point-two percent. 

However, the final investor may change as the sale of DSME will be conducted in a so-called stalking horse bid, in which the preliminary bidder suggests its price ahead of an open auction, and other bidders submit their prices later.

The KDB will place a tender notice on Tuesday and give a period of three weeks open to other bids.
