All signs, including Oscar De La Hoya’s official Twitter account page, are that the hot promotional war between Bob Arum’s Top Rank and Oscar’s Golden Boy Promotions is over.

Going further, strong indications are that there won’t even be a cold war going on between the sport’s top two promotional outfits.

Just in time for the start of summer, the Memorial Day weekend, I won’t say that “love” is in the air between Los Angeles based GBP and Las Vegas based TR but the two sides have been hitting the “like” button with increasing frequency.

All matters of dispute, both litigation and arbitration, between the two boxing behemoths will shortly disappear. And that would include Manny Pacquiao’s libel suit over drug abuse allegations, at least in connection with Golden Boy.

That’s what is partially behind Oscar’s Twitter apologies for anything hurtful he’s said in the past about both Arum and Pinoy Idol Manny Pacquiao on Thursday. De La Hoya is in a California substance abuse rehabilitation center, possibly by the beach in Malibu, and part of his rehab regimen is “making amends” to those he may have wronged one way or another.

As for Arum, who was in Washington, D.C., on Thursday, he gracefully accepted Oscar’s apologies.

“I will say this, it is a very nice gesture on Oscar’s part,” the 79 year old promoter said. “We’re grateful for that.”

Arum had a recent sitdown session with Oscar’s chief lieutenant, Richard Schaefer, as directed by their dispute mediator (the former California State Judge Daniel Weinstein) and significant progress was made in clearing the air between the archrivals.

Will this clear the way so fight fans might benefit from seeing Pacquaio fighting a GBP boxer such as Vicious Victor Ortiz or Pinoy Nonito Donaire Jr., who fled Top Rank for Oscar’s boxing band, fighting an Arum boxer?

Arum answered in the affirmative without hesitation.

“We’re moving forward and we certainly can work together,” Arum said by telephone. “Why not work together where it makes sense? Now there are no impediments.”

It remains to be seen whether Pacquiao will also drop legal claims as to defamation by Floyd Mayweather Jr.

If this “Love Train” stays on track and on schedule, it could give an impetus to making the Mayweather-Pacquiao super bout in 2012.

Pacquiao will fight archrival Juan Manuel Marquez on Nov. 12 in Las Vegas and Mayweather, inactive for 13 months, continues to be rumored to be looking to a tune up bout for the early fall.

Let the ring romance begin.
