  This study aimed to determine the factors influencing Vietnamese tea export quantities, namely, the internal factors of national tea production, productivity, and cultivated areas, and the external factors of export price and world tea export quantity (excluding Vietnam). We employed a time-series linear model to estimate the magnitude as well as the sign of the aforementioned factors on Vietnam’s tea export quantity and two Box-Cox transformations called a simple back-transformed forecast and a bias-adjustment to forecast the growth rate of the Vietnamese tea export quantity until 2030. The results suggested that except for the total domestic tea production, all the proposed factors significantly affected the Vietnamese tea export quantity. The tea export quantity of other nations around the world had a significantly negative impact on Vietnamese tea that led to Vietnam’s tea exports dropping by 34 tons on average since the other countries exported 1,000 tons of tea. The forecasted outcome suggested an upward trend of Vietnamese tea exports up to 2030. In order to sustainably develop Vietnam’s tea industry, we recommend that the government should take supportive actions such as investing in in-depth tea processing to improve Vietnam’s tea export quality, focusing on post-harvest activities, investing in organic or high-value tea rather than conventional tea, continuing to  accumulate land to support the growth of cultivated tea areas, and maintaining high productivity by using hybrid seeds.

  The traditional linear economy has created unstainable development. A circular economy (CE) is considered as a crucial means and has been adapted by many governments to achieve sustainable development goals. By narrative literature review, this article aims to discuss the concepts of linear and circular economies and CE models, examine countries’ CE development experiences, and make recommendations for successfully adapting a CE. The findings show that a CE is different from a linear one in terms of the step plan, focus, system boundaries, reuse, and business models. The CE model includes slowing and closing resource loops and a narrowing of resource flows and is based on the foundation of renewable and non-toxic resources as well as through long-lasting design, and reducing, maintaining, repairing, reusing, remanufacturing, refurbishing, recovering, and recycling. Many countries around the world have adapted a CE model with different circularity levels with the main focus to reduce waste. The paper also recommends that a CE should be percieved as the central point of socio-economic development programs and policies that must address the full cycle, from product design to production processes, consumption, and recycling rather than having only a waste reduction focus. Producers should use a CE framework as the basis for product design, manufacturing, and recycling strategies. Consumers should change their perception of CE and adjust their behaviors towards making decisions to buy and consume toward circularity. Also, there is a need to change the perceptions of policy makers and other stakeholders on the CE concepts and framework.
