QPR boss Harry Redknapp is desperate to bring in new faces next month as he looks to steer the club clear of relegation and he has made Diame one of his top targets.
Redknapp is ready to exploit Diame's release clause in his West Ham contract which is thought to be £3.5million.
All-action midfielder Diame has been a revelation for West Ham since his arrival on a free transfer from Wigan last summer.
A number of clubs have been keeping tabs on his progress at Upton Park, but QPR have made the first move to try and sign him by triggering the release clause in his contract.
West Ham had moved to try and fend off the growing interest in Diame by setting up talks aimed at taking out the release clause from his contract, but as yet no agreement has been reached.
Diame, who has been out of action since picking up a hamstring injury in the defeat by Liverpool earlier this month, is back in light training and is expected to be back playing in 10 days.
Redknapp is now hoping to be given the green light to hold talks with Diame as he sees him as the midfield powerhouse who can lead his side to safety in the second half of the season.
