What may happen to a country that only has a few natural resources?

There are a few problems and solutions to this situation. Firstly, if a country has few natural resources, it may have a bad economy. However, it can rely on trades, especially if it is a port city like Hong Kong or Singapore. Since there are a few natural resources, human resources can solve the problem as well, through education of the people to boost international cargo trade etc. However, these countries will have to depend on other countries for natural resources for projects. If these countries do not maintain good international relationships with many other countries, the country may fail as a whole since there are no resources at all to do anything.
