The convening of the 2021 Cross-Straits Entrepreneurs Zijin Mountain Summit in Nanjing, Jiangsu province, on Tuesday, shows the Chinese mainland welcomes investment and companies from the Taiwan island.

Themed "understanding new development paradigm, sharing new development opportunities", the event, which comes at a time when cross-Straits tensions are high, should send a clear signal to Taiwan compatriots that the mainland clearly distinguishes secessionists from the rest of those on the island, and its door will only open wider to Taiwan to share its high-quality development dividends.

While the United States brazenly coerces major semiconductor manufacturers from the island and the rest of the world to give it their confidential supply chain information, the summit serves as a platform giving Taiwan entrepreneurs a valuable opportunity and first-hand experience to understand how fundamentally different their treatment on the mainland is from the rogue practices of the US.

In his congratulatory message to the event, Chairman of the Chinese People's Political Consultative Conference National Committee Wang Yang conveyed Beijing's sincerity in adhering to its consistent hospitality to entrepreneurs from across the Straits. While reaffirming its resolve to achieve complete reunification of the island with the motherland in the course of national rejuvenation, Wang said there will be no change in the mainland's policy of sharing its development opportunities with Taiwan compatriots, and there will be no change in its efforts to take practical measures to help Taiwan businesses.

In urging Taiwan entrepreneurs to uphold the one-China principle and contribute to peaceful national reunification, Beijing has as a matter of fact drawn the bottom line to warn those Taiwan entrepreneurs who only covet the mainland as a market and an investment destination, while funding pro-independence forces on the island in either overt or covert ways.

Last year, despite the impacts of the COVID-19 pandemic and the obstruction of Taiwan's Democratic Progressive Party and the US, trade across the Straits hit $260.81 billion, up 14.3 percent compared with the previous year, showing the close connection and broad common interests of the two sides.

Also last year, Taiwan enjoyed $140.52 billion of trade surplus against the mainland, which is its largest trade partner.

Taiwan enterprises will benefit from the improvement of the business environment on the mainland, and the mainland's pursuit of high-quality development. The two sides have huge potential and complementarity to tap in many areas.

People on both sides of the Straits share bonds of kinship, and expanding and deepening exchanges and cooperation is in their common interests. Taiwan businesses should draw a clear line with Taiwan "independence" and secessionist forces so they can play their part in improving the well-being of compatriots on both sides of the Straits.
