Answer: Arnis, also known as Kali or Eskrima/Escrima, is the national martial art of the Philippines. The three are roughly interchangeable umbrella terms for the traditional martial arts of the Philippines ("Filipino Martial Arts", or FMA), which emphasize weapon-based fighting with sticks, knives, bladed weapons, and various improvised weapons, as well as "open hand" techniques without weapons. There have been campaigns for arnis to be nominated in the UNESCO Intangible Cultural Heritage Lists, along with other Philippine martial arts. As of 2018, UNESCO has inscribed nine martial-arts–related intangible heritages.
