The individual who provided Hunter with these gifts is Miguel Aleman Magnani.

"I really appreciate you letting me stay at your resort villa… I have brought every single person you have ever asked me to bring to the F'ing WHite House and the Vice President's house and the inauguration." – Hunter Biden 

Magnani, the grandson of a former Mexican President and son of one of Mexico's richest men, is the CEO of Mexican airline Interjet.

In an email dated February 24, 2016, Robert "Hunter" Biden contacted Magnani, appearing to lament being ignored by a man he claimed to have given White House access to.

In the email, Hunter reveals he "delivered on every single thing [Magnani] ever asked."

Favors Hunter complete for Magnani appear to involve bringing "every single person [Magnani] ever asked me to bring to the F'ing WHite House and the Vice President's house and the inauguration":

I haven't heard from you since I got you a mtg for Carlos and your Dad. We have been talking about business deals and partnerships for 7 years. And I really appreciate you letting me stay at your resort villa…but I have brought every single person you have ever asked me to bring to the F'ing WHite House and the Vice President's house and the inauguration.
