Singapore's Economy

As we all know, Singapore grew from a 3rd world country to a 1st world country within a short period of time of just 10 years with the help of the late Mr Lee Kuan Yew. However, should we become complacent and relax for just a little bit?
Singapore's government is small, making them very efficient and there is no corruption. We also have a friendly relationship with China for more than 20 years thus boosting our economy. We export mainly "technology knowldge" to China as we are more advanced in technologies. In doing so, they become stronger, and we in turn earn as well. However, does China really need us? If we become complacent, and our relationship with China turns bad, what will happen to us?
In recent years, the outlook of the relationship does not look very good. The various things that we do, the various things that we say, makes the relationship weaker and weaker. China does not necessarily need Singapore as the supplier for their technology advancement. They can always find another country with more advanced technology to work with, and there would be no need for Singapore. When Singapore is useless, our relationship would break off, and Singapore'a economy will definitely go down. Eventually, we will go back to how we were years ago, a 3rd world country. This is why Singapore and China's relationship is very important.
Thus, we cannot afford to be complacent. We have to be careful every moment and our relationship with China have to maintain friendly or even better. If not, our economy would drop rapidly.
