I would reccomend that you build 3 electronic manufactories at the start, sell electronics, invade a country and take it's land and money and build a fertelizer, steel and motor manufactory and after that build consumer goods factories. Electronics and consumer goods are great for economy and selling. You can sell 110 consumer goods to China, 100 to Brazil, 70 to Japan, 160 to India and the United States both, If you manage to sell to atleast one of these countries consumer goods, it is guaranteed that you will get atleast 10M income in early game.
