musical genres that have influenced other traditional musical styles in the region. String instruments are also popular in the region. On 18 November 2010, UNESCO officially recognised the angklung as a Masterpiece of Oral and Intangible Heritage of Humanity, and encouraged the Indonesian people and government to safeguard, transmit, promote performances and to encourage the craftsmanship of angklung making. Writing The history of Southeast Asia has led to a wealth of different authors, from both within and without writing about the region. Originally, Indians were the ones who taught the native inhabitants about writing. This is shown through Brahmic forms of writing present in the region, such as the Balinese script shown on split palm leaves called lontar (see image to the left – magnify the image to see the writing on the flat side, and the decoration on the reverse side). The antiquity of this form of writing extends before the invention of paper around the year 100 in China. Note each palm leaf section was only several lines, written longitudinally across the leaf, and bound by twine to the other sections. The outer portion was decorated. The alphabets of Southeast Asia tended to be abugidas, until the arrival of the Europeans, who used words that also ended in consonants, not just vowels. Other forms of official documents, which did not use paper, included Javanese copperplate scrolls. This material would have been more durable than paper in the tropical climate of Southeast Asia. In Malaysia, Brunei, and Singapore, the Malay language is now generally written in the Latin script. The same phenomenon is present in Indonesian, although different spelling standards are utilised (e.g. 'Teksi' in Malay and 'Taksi' in Indonesian for the word 'Taxi'). The use of Chinese characters, in the past and present, is only evident in Vietnam and more recently, Singapore and Malaysia. The adoption of chữ Hán in Vietnam dates back to around 111 BC when it was occupied by the Chinese. A Vietnamese script called chữ Nôm used modified chữ Hán to express the Vietnamese language. Both chữ Hán and chữ Nôm were used up until the early 20th century. Sports Association football is the most popular sport in the region, with the ASEAN Football Federation, the region's primary regulatory body, formed on 31 January 1984, in Jakarta, Indonesia. The AFF Championship is the largest football competition in the region since its inaugural in 1996,
