Hell is on the verge of breaking loose once again as Sands China chief Sheldon Adelson and Galaxy Entertainment Group (GEG) find themselves locked in yet another heated word war.

GEG came out swinging on Friday and– without mincing words – calls Adelson “impolite” and “unprofessional” in a bitter response to the feisty American casino mogul’s remark that the Galaxy Phase 2 and Studio City are not as good as his new project, The Parisian, according to Macau Business Daily.

In an act of retaliation, GEG takes a jab at Adelson’s irresponsible comment, saying that it is deeply disappointed with the Sands China executive.

“Galaxy Entertainment Group (GEG) would like to express its deep disappointment in his unprofessional behavior.  Belittling the competition through unfair comments benefits no one,” according to the GEG statement sent to the news agency.
