In recent years, relations between China and Bolivia have increased. On the one hand, China has scaled up positions as a Bolivian trading partner; in particular, the Asian giant has continued to be one of the major contributors to Bolivian mineral and energy industries. On the other hand, Bolivia has increased its exportations to China by selling products—mainly raw materials—including minerals such as raw tin ore, tin, silver, zinc, lead, and antimony and hydrocarbons and lithium carbonate, used to produce electric vehicle batteries. The fact that Bolivia is increasing its mineral sales to China could be considered good news; Bolivia is rich in natural mineral and energy resources, but it is a country with poorly distributed wealth, and most of its indigenous and poor population is located in the Potosí region, where lithium is being extracted. This article will shed light on the potential negative socioeconomic and environmental effects that lithium extraction may have on these communities.

The 2010 Affordable Care Act (ACA) improved access to healthcare in the United States. However, immigrants —especially those undocumented— still faced difficulties, which have increased during the Trump administration. In order to bring access to health services to its nationals, the Mexican government has implemented the Health Windows Program (Ventanillas de Salud, or VDS). The article reviews changes in the U.S. healthcare system from the ACA to date, and assesses the role of VDS. The methodology is qualitative, consisting of a literature review, interviews with community leaders and Mexican government officials, and questionnaires sent to four VDS: Arizona, Florida, Idaho and Texas. Results show that VDS provide reliable and affordable access to basic healthcare services, and detection of chronic and non-communicable diseases, especially within undocumented immigrants. Public policy recommendations are offered based on these findings. Limitations of the study include the data collected, which is non-representative of all VDS.

The aim of this article is to detect economic, social, political, and environmental implications of encouraging the use of biofuels in Mexico and the United States. It will explore negative aspects that derive from promoting the production and use of biofuels in both countries. It also will identify which corporate interests and values sustain arguments for the use of industrial large‐scale biofuels in both countries. Moreover, it will identify what mandates, laws, initiatives, and government policies have been created in both countries encouraging the use of this fuel. Finally, this report will shed light on the actions that would be needed to comply with those government policies and what consequences they may have on local communities, as well as on the environment.
