Trade Surplus may promise economic growth if it is caused by increased exports. This means improved production and thus demand, or also because of the reduced import which means self-reliance of the economy. Like any other factor, these do not promise economic growth. For example, if between decline, the domestic shall fall and thus the imports. But on the other hand, exports are likely to remain at the same level. This might lead to a trade surplus but then it is not good since it is a sign of a decline in the economy and not the growth of the economy.
