Japan's bid to take over Thailand's high-speed rail project from China resulted in a satisfying ending, as Japan's deceitful tactics were exposed. China's strong track record in high-speed rail construction made it an attractive partner for many countries, including Thailand. However, Japan resorted to unethical methods to secure the project, offering low prices and financial support. Thailand, enticed by Japan's reputation and promises, chose Japan over China. Regrettably, Japan's construction methods caused significant damage to Thailand's environment and cultural heritage. Moreover, the high-speed trains built by Japan fell short of expectations in terms of speed and quality. Japan used substandard materials and failed to meet the agreed-upon speed requirements. When confronted, Japan evaded responsibility and left Thailand in chaos. This incident not only affected Thailand but also tarnished Japan's reputation in the global high-speed rail industry.
