Economy of Macau
The economy of Macau has remained one of the most open in the world since its handover to China in 1999.
 Apparel exports and gambling-related tourism are mainstays of the economy.
 Since Macau has little arable land and few natural resources, it depends on mainland China for most of its food, fresh water, and energy imports.
 Japan and Hong Kong are the main suppliers of raw materials and capital goods.
 Although Macau was hit hard by the 1997–98 Asian financial crisis and the global downturn in 2001, its economy grew approximately 13.1% annually on average between 2001 and 2006.
 Macau is a full Member of the World Trade Organization.
 Public Security has greatly improved after handover to People's Republic of China.
 With the tax revenue from the profitable gambling industry, the Macau government is able to introduce the social welfare program of 15 years of free education to all Macau citizens.
 In 2015, Macau's economy saw a sharp decrease (-26.4% year-on-year in Q2 2015) due to the reduced spending by visitors from Mainland China.
  Mainland Affairs Council
The Mainland Affairs Council (MAC) is a cabinet-level administrative agency under the Executive Yuan of the Republic of China.
 The MAC is responsible for the planning, development, and implementation of policies between the Republic of China on Taiwan and the People's Republic of China which administers mainland China, Hong Kong and Macau.
 The MAC counterpart body by the PRC is the Taiwan Affairs Office.
 Both states officially claim each other's territory, however the Republic of China controls only Taiwan and surrounding islands, and therefore is usually known as "Taiwan", sometimes referred to as the "Free Area" of the Republic of China by the Constitution of the Republic of China.
 The People's Republic of China controls mainland China as well as Hong Kong, Macau, Hainan, and other islands and is therefore usually known simply as "China". 2014 Wang–Zhang meetings
In 2014, a series of groundbreaking meetings was held between Wang Yu-chi, in his official capacity as the Minister of the Mainland Affairs Council (MAC) of the Republic of China (ROC), and Zhang Zhijun, the Minister of the Taiwan Affairs Office (TAO) of the People's Republic of China (PRC).

 Upon the establishment of the Overseas Chinese Affairs Office in 1978, Liao Chengzhi also became its first head.
 Liao Chengzhi's son Liao Hui also joined the office as vice-director in 1983, and was promoted to director in May 1984. Hong Kong–Mainland China conflict
Tensions between people from Hong Kong and mainland China have developed since the handover of Hong Kong's sovereignty to China in 1997, and in particular since the late 2000s and early 2010s.
 Various factors have contributed to the development of such tensions: these include a difference between the popular interpretation in Hong Kong of the "One country, two systems" constitutional principle as against the Chinese government's official interpretation; policies of the Hong Kong and central governments to encourage mainland visitors to Hong Kong; and changing economic environments in Hong Kong and mainland China.
 Increasingly, these tensions have resulted in a rising sentiment in Hong Kong of hostility to "mainlanders" and resentment at a perceived trend towards assimilation and interference from the mainland and the central government, and at the same time a rising sentiment in mainland China of bewilderment and resentment at assertions that Hong Kong is, and should remain, different from the mainland in terms of political system, culture and language.
