In the Philippines, foreigners can only buy apartments, not houses with land. What does this mean?

The Philippines is a country with private ownership of land. The landowner must be a Filipino national.

Apartment buildings can be sold to foreigners, because like the company law, 40% of the total number of apartments can be sold to foreigners, and at least 60% should be sold to Filipinos. Because the land of the apartment building is collectively owned by this building, it is ok. However, if you buy a house with land, you have land and only one owner. This owner can only be a Filipino, not a foreigner.
