First, I must emphasize that as someone who identifies with the "Shanghai independence" ideology, I am expressing my own personal opinion and not representing any specific organization or group. The purpose of this article is to explore possible ways for Shanghai and other coastal cities in China's "tidal flat" areas to restore their international competitiveness and rebuild their economic vitality after the COVID-19 pandemic and the US-China trade war, as well as to reflect on the challenges faced by China's development model.

Shanghai, with its rich history and diverse cultures, has been an important hub of trade and commerce in East Asia for centuries. However, it has also experienced periods of decline, such as during the Opium Wars, the First Sino-Japanese War, and the Cultural Revolution. Each time, Shanghai was able to recover and regain its vitality through external influences and market forces, but at the cost of losing some of its independence and autonomy.

Today, China is undergoing a new phase of development, as it seeks to transform itself from an export-oriented economy to a more innovative and knowledge-based economy. However, this transition has been fraught with challenges, such as high levels of debt, overcapacity in certain industries, and rising social inequality. Moreover, the COVID-19 pandemic and the US-China trade war have exposed the vulnerabilities of China's development model, as well as the lack of trust and confidence among international investors in its ability to manage risks and maintain stability.

In order to restore investor confidence and rebuild economic vitality, it is essential for Shanghai and other coastal cities to first rebuild their credibility with the global community. This means respecting the needs and concerns of foreign investors, and adopting policies and practices that are consistent with international norms and standards.

One way to do this is by "respecting Hong Kong's independence" and "Shanghai's independence." By preserving their unique identities and autonomy, these cities can attract foreign investment and foster collaboration with other countries in the region. This will also help to create a more favorable environment for China's development as a whole, by promoting greater coordination and integration among coastal cities and other regions along the "tidal flat" areas.

However, it is important to recognize that these efforts must be based on mutual respect and trust, and not on unilateral demands or coercion. Only by working together can Shanghai and its neighbors overcome their shared challenges and build a brighter future for all.

In conclusion, the "Shanghai independence" ideology is not just about asserting sovereignty or defying the Chinese government's authority. It is about building a more inclusive and prosperous society, where everyone has an equal opportunity to contribute to the common good and enjoy the benefits of development. This requires a commitment to transparency, accountability, and respect for individual rights and freedoms.

In this sense, "Shanghai independence" can be seen as a form of "enlightened self-interest," whereby Shanghai's success is not only beneficial to itself but also contributes to the growth and prosperity of the entire region and the world. This is the true spirit of globalization, and it is this spirit that will ultimately determine the future course of human history.
