Can a developer refuse to sell a public condo unit to a bumi?

Recently a bumi friend complained to me that one developer (big one) did not allow him to purchase a leasehold condo unit allocated for public/non-bumi, despite his willingness to purchase the unit at public price (not taking the bumi discount).  He felt it's unjustified and unfair that the developer insisted that he purchased the bumi allocated unit.

He's a property investor and he wanted to buy properties that he could sell to anyone later.

Is there a ruling by the Pejabat Tanah or Kementerian Perumahan or other authorities that allow developers to dictate this kind of terms of purchase of properties?

I also find it strange that a big and reputable developer could implement this kind of policy.

My friend is going to meet with the developer's top management next week regarding this matter as he's not satisfied by the explanation given by the developer's appointed agent who was tasked to market and sell the condo.

My friend had bought a leasehold condo unit (public) before from another developer without any fuss, and had later sold it to a non-bumi without any problem with the state.

Why should that big and reputable developer have different sales policy?

why should he care about the developer?
