The three steps to achieve the aim to exploit natural resources of Vietnam were :
(i) The French began building canals and draining lands in the Mekong Delta to increase cultivation. As a result of irrigation works, the rice production increased. Vietnam became the third largest exporter of rice in the world.
(ii) Trans Indo-China rail network was constructed. It linked the Northern and Southern parts of Vietnam and China. Another line linking Vietnam to Siam (Thailand), via the Cambodian capital Phnom Penh was also built.
(iii) To ensure higher level of profits, French pressurized the government to develop infrastructure.
