The authors write that Vietnam will play host to a critical meeting between Donald Trump and Kim Jong Un, and it will benefit from their peace efforts regardless of the outcome.

Mahsa Rouhi compares and contrasts the situations with Iran and North Korea and warns of the consequences.

"...Iran's turn toward China and Russia leave the United States with less leverage for future negotiations on any issue, making it less and less likely for Iran to agree to cooperate with the United States or its allies. Thus, it is crucial to rethink these policies and come up with a more feasible plan."

"Ukraine's denuclearization had been a controversial issue even as it was negotiated, leaving bitter traces in the country's political and public discourse. As a student of political science in Kyiv in the mid-1990s, I remember being outraged by the sense of injustice: how could the states that rely on their own nuclear deterrents demand the nuclear disarmament of others? More so that one of these states, Russia, has never fully come to terms with Ukraine's independence. Since then, I came to research a doctoral dissertation on the denuclearization of post-Soviet successor states and, in the process, learned a great deal about Ukraine's nuclear disarmament that dispelled many of my preconceptions."

Scientists from three universities demonstrate that buying a product made in China causes significantly higher carbon dioxide emissions than purchasing the same product made elsewhere.

The authors findings suggest that overestimation of China's emissions in 2000–2013 may be larger than China's estimated total forest sink in 1990–2007 or China's land carbon sink in 2000–2009.The revisions of the Chinese emissions are substantial enough that they may lead to adjustments in the Global Carbon Cycle.

The magnitude and growing annual rate of growth of China's carbon emissions make this country the major driver of global carbon emissions and thus a key focus for efforts in emissions mitigations. This report presents independent data on China's carbon emissions from 1950–2012, and provides a basis to support mitigation efforts and China's low-carbon development plan.
