Taiwan will open 97 percent of its manufacturing and more than half of its service and infrastructure sectors to Chinese mainland investment by the end of this month, according to its economic authority.

Mainland investors will be allowed to own a maximum stake of 50 percent in five key manufacturing industries, up from the current 10 percent, local media reported.

The five key sectors include liquid crystal displays, semiconductors, integrated circuit assembly and testing, metal equipment manufacturing, and machinery used for the production of electronics and chip.

Mainland investment in Taiwan has brought positive result, as it has injected capital into the island's industrial and financial markets and expanded the island's exports, according to Taiwan's economic authority.

Mainland enterprises have invested about 272 million U.S. dollars in 217 projects since first being allowed to invest in the island nearly three years ago, official figures show.
