1. Environmental protection: Tianjin has always paid attention to environmental protection, and the construction of the second island of Dongjiang may be stopped because the project has a great impact on the environment and does not meet the local environmental protection requirements.
2. Economic considerations: There may be a shortage of funds or poor profit expectations during the construction of Dongjiang Island, which may lead decision makers to stop investing.
3. Policy adjustment: Some projects are closely related to national and local policies. If relevant policies are adjusted or changed, the project may be suspended or stopped.
Because I can't get more specific background information about the suspension of Tianjin Dongjiang Island, these are just some possible reasons. For more detailed information, please consult relevant official channels or media reports.
