If only other peace treaties could pan out this smoothly.

Following a brawl between Nepalese Sherpas and famous European climbers atop Mount Everest, the two parties have signed a handwritten agreement to shake hands, make up and climb alongside one another.

The fight occurred Saturday, after Italian Simone Moro, who has climbed Everest four times, and Uelie Steck of Switzerland, who has broken climbing records, ignored requests from nearby Sherpas to not climb while they were rigging ropes up the mountain.

The Nepalese told the team not to scale the side of Everest while they were fixing the ropes, but Steck and Moro did anyway-some ice fell on the Nepalese, which made them even more angry, according to eyewitnesses.

Later that evening, the Sherpas rushed the climbers' tents, throwing rocks, kicks and punches when the two men eventually emerged.

Those watching the fight called it "terrifying."

But by Tuesday, both sides apologized to one another, putting it in both English and Nepalese writing.

"Both parties have realized their errors and apologized to each other in front of those present," reads the note, which CNN acquired by way of the Nepal Mountaineering Association. "Both parties agreed to help each other in the future to make successful each others goals."

At least 28 signed the agreement, including a photographer who was documenting the two climbers' ascent named Jonathan Griffith. He was with Steck and Moro when the argument broke out.

Griffith told the Telegraph that an influx of funds has changed the experience on Mount Everest, and angered the Sherpas.

"They're angry at this financial gap on their mountain," Griffith said. "These commercial trips are based on a lot of luxury and getting you up the mountain and a lot of these Western clients don't even know what the names of their Sherpas are."
