Which were provisions of the open door policy

"The 1899 Open Door notes provided that (1) each great power should maintain free access to a treaty port or to any other vested interest within its sphere, (2) only the Chinese government should collect taxes on trade, and (3) no great power having a sphere should be granted exemptions from paying harbour dues or railroad charges."
