There is no similarity. The places that support massive rice cultivation, like southeastern China, Vietnam, Korea, etc. do not have large petroleum reserves. Conversely, most areas that do have oil wells and offshore drilling are too arid (relatively speaking) for rice to grow well.
Oil mining is done by mechanics while rice cultivation is manual.
The Tang Dynasty (618-907) Vietnam had many successful tactics of growing different strains of rice. With their surplus of rice, many different countries wanted to invade them to know how Vietnam was so successful at growing rice. To ensure that their empire was safe, they sold rice continuously to other nations and empires, including China.
