Economic models are changing in development goals and Vietnam has also entered a new stage of development. Building ecological industrial parks and converting existing industrial parks into ecological industrial parks has become an urgent matter to adapt to the new circumstances and requirements. To increase the number of new-style industrial parks and green industrial parks to welcome high-quality investment flows, National Land Use Planning for the 2021-2030 period aims to promote and encourage the development of industrial parks and export processing zones under a circular model, with low greenhouse gas emissions. However, the legal framework for developing such parks is not yet complete, so there is some degree of confusion surrounding implementation.
