A state-controlled Chinese company's plan to invest about $2 billion in the Taiwanese semiconductor industry has intensified election-year concerns in Taiwan that could set back China's ambitions to develop a leading-edge microchip industry.

The dispute revolves around recent Chinese inroads into Taiwan's chip sector, a major source of Taiwanese economic growth, pride and an important supplier of components for the world's gadgets. It is part of a broader debate in Taiwan—an island that Beijing's political leaders consider a renegade province—about growing economic ties with the mainland.

On Thursday, Xu Jinghong, chairman of state-controlled conglomerate Tsinghua Holdings Ltd., addressed Taiwanese worries about Chinese investment in its chip industry. Tsinghua Holdings' chip arm, Tsinghua Unigroup Ltd., has in recent days unveiled plans to invest to Taiwanese companies.

"What's so bad about cooperation between the mainland and Taiwan?" he said. "If Taiwan can continue to close itself, it will lose opportunities for future development."

Mr. Xu was responding to questions about Tuesday comments from Tsai Ing-wen, the Taiwanese opposition leader who is the favorite to become Taiwan's next president in elections next month. Citing Tsinghua Unigroup's ties to Beijing, she said she believed the deals were part of broader efforts to control Taiwan's semiconductor sector.

"This is a very, very large threat to Taiwan's industry," she said in Taiwan. "If these issues are not clarified, I don't think there is any room for opening up."

Ms. Tsai's wariness reflects broader sentiment in Taiwan. Her main rival Eric Chu is from the ruling party, the Kuomintang, which traditionally supports more cross-strait investment. But Mr. Chu has taken an even stronger stance than Ms. Tsai against China chip investment ahead of the election, which analysts say is a play to win voters.

"Tsinghua Unigroup has announced so many rapid-fire investments, it scares the people," said Mark Li, a Bernstein Research technology analyst. "It's too fast, too much."

Speaking on the sidelines of China's Wuzhen Internet Conference, Tsinghua Holdings's Mr. Xu said his company is seeking "a win-win situation." "It is not, as some narrow-minded people in Taiwan would say, that the mainland is trying to occupy or invade Taiwan."

The back-and-forth illustrates the increasingly complex relationship between China and Taiwan. Chinese President Xi Jinping and Taiwanese President Ma Ying-jeou met in November, the first meeting between the leaders of the two governments since the island and the mainland split in 1949. Trade has also grown. At the same time, China's Foreign Ministry on Thursday criticized U.S. approval of its first major sale of weapons to Taiwan in four years.

Both the Chinese and Taiwanese chip industries see benefits in cooperation. China needs Taiwan's technology to build advanced chips. Taiwanese companies need Chinese capital and could benefit from lower-cost labor if it made more chips on the mainland.

Tsinghua Unigroup has become China's semiconductor champion. It has announced investments totaling more than $20 billion so far this year, making it one of the chip sector's most acquisitive companies. It is part of China's efforts to nurture a chip industry so that it no longer relies on foreign suppliers.

Tsinghua Unigroup recently announced plans to become the largest shareholder in three Taiwan chip packaging companies: Siliconware Precision Industries Co., ChipMOS Technologies Inc. and Powertech Technology Inc. The proposed deal with Siliconware—known as SPIL—was controversial due to SPIL's status in Taiwan's tech industry and importance as an Apple Inc. supplier. SPIL's largest shareholder, the Taiwanese firm Advanced Semiconductor Engineering Inc., offered to buy out the rest of SPIL at Tsinghua Unigroup's bid price.

While Chinese investment is allowed in Taiwan's chip packaging sector, chip design companies are still off limits. Analysts say a swing factor is whether Mr. Ma, the Taiwanese president, will try to open up chip design investment before his term ends in May, as some Taiwanese chip design firms have requested, although the tight timeline would make it difficult.

T.C. Tu, general director of the competitiveness center for Taiwan's state-funded Industrial Technology Research Institute, said China will become a major competitor to Taiwan in microchips within a decade and said Taipei should carefully consider growing industry ties.

"Taiwan should cooperate with China in chips in areas where China dominates the market, but maybe should refrain in areas where Taiwan sells mostly to Europe or the U.S.," he said.

Sun Lih-chyun, a spokesman for the executive branch of Taiwan's government, said Thursday that Tsinghua Unigroup has yet to officially submit its investment plans for government review. When it does, Taiwanese regulators will consider whether it poses a risk to Taiwan's chip sector, he said.

Tsinghua Unigroup Chairman Zhao Weiguo said in a statement Thursday that his company hasn't been in contact with Ms. Tsai's party. He said Tsinghua Unigroup isn't a government department and he hopes the company will be treated the same in Taiwan as companies from other countries are.

"After all, we and Taiwanese people are all Chinese, we have the same roots and ethnicity," he said.
