The goal is, among other things, to increase the prize money to prevent players from participating in the LIV tour instead.
The PGA will try to establish three new international tournaments.
Both tours have been clear in their position on players who will transfer to the LIV tour. The PGA has therefore banned a number of players from its tournaments so far.
In addition, a clearer set of rules will be drawn up for how, and when, one can move between the PGA and the European Tour.
Starting in 2023, the top ten in the European Tour summary will participate in PGA tournaments the following season.
“We are very pleased with this expanded partnership,” said PGA Director Jay Monahan.
