Controversy whether a country will gain from trade liberalisation or not is proved by the results of this study.

The main commodities of Indonesia which have high competitiveness in the market of ASEAN and ANZ are oil and gas i.e, natural gas, petroleum oil and coal, and non-oil and gas i.e, crude palm oil and cigarette.
