One of the ways Japan build its post-war economy was a peculiar method on how they organized both internal competition and exports.
1) In the internal market, Japan applied strong protectionism to impede imports from foreign firms.
2) They selected a number of national champions (usually between 5 and 8) with a similar structure of suppliers
3) National champions competed furiously for market share, without one ever grabbing a too big share
4) As result of this fierce competition, the Japanese companies became competitive in the international market
5) The companies began to export, not individually, but as a syndicate -in a collaborative way- to gain critical mass
Japan had huge success with this stratagem. Also Keiretsu - which is a Japanese term, for a strong relationship, even mutual equity stakes between a group of companies - is a strong bond when working and trading internationally. This system is still in place in the Japanese economy.
I believe a sovereign economy should consider the Japanese method of building up entire industries, it has worked before successfully and can work now.
