Non-trade overseas investment by Mainland China's enterprises increased from zero in 1979 to more than four billion US dollar in 1995. While this growth is extremely rapid, it accounts for only a very small proportion of the world's overseas investment. There are unique features of mainland China's overseas investment including state-owned enterprises as the main investors; investment concentration in few countries such as Canada, the United States and Australia, and more than 50% ownership share in most joint venture cases. This overseas investment is inspired by four major reasons: (1) to avoid country quotas so as to increase their market share in industrial nations, (2) to obtain high technology, (3) to obtain natural resources, and (4) to get foreign financial resources. In some cases, however, mainland China's government sought to weaken Taiwan's foreign diplomatic relationships through its concession on favorable overseas investment.
