The power of his intellect is reflected in his
genius in realizing the stream of globalization at that time and
can be seen from the fact that King Naresuan had enhanced economic
strength which was the happiness and wealth of the citizens and was
an essential factor for warfare to protect the country. He revived
marine trading that had been rather inactive due to chronic Ayuddhaya-Burmese
wars. It can be said that the economy during the reign of King Naresuan
was prosperous and trade with foreign countries was expanded widely,
and this brought great income into the country which led to recovery
and creation of peace in the country eventually.
