Ochoku had a relationship with Garling. He carried out the kidnapping of Shakky for the World Government. Garling said he arranged it. So there might already have been direct contatct. Ochoku even dressed like them. As a Rocks Pirate already, he wore a white cravat. Not typical pirate attire, more so that of nobles.
When he took over pirate island, he must have governed it for the benefit of the world government. Otherwise they wouldn't have allowed im to rule it for 40 years. They tried to hire Rocks to clean the island before. Ochoku probably smuggled goods and slaves to Maryjoa. Perhaps he even became a God's Knight.
Ochoku having have had regeneration would explain why Blackbeard needed outside help to get rid of him. We know that Law was involved. He took 100 hearts in the process. Ochoku probably had a mechanical heart like Super Sommers. Thus it would have been easy for Law to deal with him.
