I think the common between low-latitude countries would be people's skin color and  If you compare the Philippines and its neighboring countries, they have more or less similar physical attributes. Typical Filipinos looked similar with Indonesians.
For Southeast Asia, i would also consider religion is common between the two. Both the Philippines and the other Southeast Asian countries such as Indonesia, Malaysia, and Thailand, they have a large number of Muslim settlers while other tropical countries in South America, these countries have similar Spanish ancestry just like the Philippines.
        
                    
             
        
        
        
The Guayas River flows through Guyaquil, which is the largest city in
Ecuador. However, it is not the capital city, which is Quito. The Guayas
River has it's name, because it flows through the Guayas province. The
Guayas River does not flow into any ocean or sea. Guayaquil is also the
most populated in Ecuador. The city underwent relatively recently an
"urban renegation" to attract more tourists to that particular region of
Ecuador. This was also to help boost the economy, since at the moment
it mostly consists of small and medium businesses, agriculture and
aquaculture.
