While Chinese primary schools were allowed to retain Chinese as the medium of instruction, Chinese secondary schools are required to change into English-medium schools. Over 60 schools converted to become National Type schools.

A tough military response was needed to end the insurgency and bring about the establishment of an independent, multi-racial Federation of Malaya on 31 August 1957. On 22 July 1963, Sarawak was granted a self - governance. The following month on 31 August 1963, both North Borneo and Singapore were also granted self - governance and all states began to formed Malaysia on 16 September 1963.

Document 8: British Empire: Following the defeat of Japan in the Second World War, anti-Japanese resistance movements in Malaya turned their attention towards the British, who had moved to quickly retake control of the colony, valuing it as a source of rubber and tin. The fact that the guerrillas were primarily Malayan-Chinese Communists meant that the British attempt to quell the uprising was supported by the Muslim Malay majority, on the understanding that once the insurgency had been quelled, independence would be granted. The Malayan Emergency, as it was called, began in 1948 and lasted until 1960, but by 1957, Britain felt confident enough to grant independence to the Federation of Malaya within the Commonwealth. In 1963, the 11 states of the federation together with Singapore, Sarawak and North Borneo joined to form Malaysia, but in 1965 Chinese-majority Singapore was expelled from the union following tensions between the Malay and Chinese populations. Brunei, which had been a British protectorate since 1888, declined to join the union and maintained its status until independence in 1984.
Document 9: Portuguese Malacca: The Dutch with their local allies assaulted and finally wrested Malacca from the Portuguese in January 1641. This combined Dutch - Johor - Aceh efforts effectively destroyed the last bastion of Portuguese power, reducing their influence in the archipelago. The Dutch settled in the city as Dutch Malacca, however the Dutch had no intention to make Malacca their main base, and concentrated on building Batavia (today Jakarta) as their headquarters in the orient instead. The Portuguese ports in the spice - producing areas of Mollucas also fell to the Dutch in the following years. With these conquests, the last Portuguese colonies in Asia remained confined to Portuguese Timor, Goa, Daman and Diu in Portuguese India and Macau until the 20th century.
Document 10: Myanmar: British colonial rule introduced Western elements of culture to Burma. Burma's education system is modelled after that of the United Kingdom.

Document 11: Dutch Malacca: Dutch Malacca (1641–1825) was the longest period that Malacca was under foreign control. The Dutch ruled for almost 183 years with intermittent British occupation during the Napoleonic Wars (1795–1818). This era saw relative peace with little serious interruption from the Malay kingdoms due to the understanding earlier on forged between the Dutch and the Sultanate of Johor in 1606. This time also marked the decline of the importance of Malacca. The Dutch preferred Batavia (present day Jakarta) as their economic and administrative centre in the region and their hold in Malacca was to prevent the loss of the city to other European powers and subsequently the competition that would naturally come with it. Thus in the 17th century, with Malacca ceased to be an important port, the Johor Sultanate became the dominant local power in the region, due to the opening of its ports and the alliance with the Dutch.
