QPR owner Tony Fernandes would not confirm the signing but told Reuters at the British Formula One Grand Prix that the club would be making an announcement on Monday.
"Lots is happening in the club. We've signed five players, we've got a few more to announce," said the Malaysian aviation entrepreneur.
South Korea is also an important growth area for Fernandes' AirAsia airline.
"What [manager] Mark [Hughes] would like to do is have two people in each position," he said. "Now whether we get to that situation..."
QPR are also planning a new 40-45,000 seater stadium in West London and have hired architects Populous, who designed the new London Olympic Stadium and Silverstone's Wing pit and paddock complex.
That would be more than double the capacity of QPR's current Loftus Road home. Fernandes said those plans were looking good and a preferred site had been identified in the White City area.
"We could have sold 20,000 season tickets easily and I think with the investment in the squad and some of the ambitions that we have, and the catchment area that we are in, I don't envisage that it will be difficult to fill up," he added.
He said Populous would also be helping him with his new Caterham Formula One team headquarters at Leafield in central England as well as the development of QPR's new training ground in Ealing, west London.
"I'd like to try and make a Formula One, Caterham Cars, QPR kind of concept with maybe a hotel in the middle, kind of health and leisure," he added.
