Despite the fact that considerable mineral wealth is found in Southeast Asia, heavy industry is little developed. This is because:

1. Most of these countries were under colonial powers who did not want industry to develop.

2. Coal and iron ore have not been found in the same country.

3. Government policy after end of colonialism also discouraged the development of heavy industry

4. Market within and outside the country was lacking.

Which of the above statements is/are correct?
