Colonized by the Portuguese in the 16th century, Macau was the first European settlement in the Far East.

In this agreement, China promised that, under its "one country, two systems" formula, China''s socialist economic system would not be practiced in Macau, and that Macau would enjoy a high degree of autonomy in all matters except foreign and defense affairs for the next 50 years.
