Lee Kuan Yew visited China in 1980, 1985 and 1988, covering cities from Shenzhen, Xiamen, Dalian, Kunming to Wuhan. Having been to different parts of the country, he was able to understand and compare their unique characteristics. He sometimes revisited the same cities so that he could observe their developments and changes. When Lee met the younger generation of Chinese leaders, he noted that their approach and thinking were different from those of their predecessors. He also brought the core members of Singapore's next generation of leaders on his visits, hoping to sustain relations between the two countries.

During these 10 years, Singapore and China implemented their trade and economic cooperation plans, with Singapore establishing a trade representative office in China.

Following his visit in 1988, Lee told Singapore reporters that China and Singapore had established mutual trust and understanding. China knew that Singapore was consistent and credible, while Singapore knew that China did what it said it would do.
