The increasing global economic, social, and political interdependence has led to expanding trade in goods and services. The WTO facilitates international trade by providing a nondiscriminatory trading environment to all member states. Afghanistan started the WTO accession in 2009 and joined as the 164th member on December 18, 2015. This piece examines the legal implications of the WTO membership on Afghanistan’s trade and economy. While membership will expand trade, attract foreign investment, and increase Afghanistan’s market share worldwide, it also means harmonizing domestic regulations with the WTO standards. In addition, lower tariffs on imported goods threaten local industries, leading to job losses, industrial shrinkage, and reduced government income. The study’s findings show that, despite short-term vulnerability, joining the WTO has long-term benefits such as economic growth, increased investment, reduced cost of living, and fairer trade structure.

Asian economic potential draws world attention. Recently, China challenges the US’s economic and political dominance which prompted the US-China trade war. Afghanistan and other Arab nations struggled for decades amid an informal US colony after Saddam Hossain’s fall. After the US troops left Afghanistan in 2021, the Taliban took over it. Afghanistan’s trade and military advantage make it vital as middle east geopolitics alter. This has been noticed by China. China-Afghanistan military cooperation improves trade. All in Eurasia is seeing China penetrate global value networks and the Belt and Road supply chains. The 21st century’s Silk Road connects Eastern Afghanistan’s Wakhan Corridor. China-Afghanistan cooperation along the Wakhan Corridor is the key to the success of the Silk Road initiative. China-Afghanistan wants to use the corridor more, which has been a commerce and military battleground. The essay discusses China- Afghanistan strategic relations along the Wakhan Corridor from a legal and strategic perspective.

The Indian Ocean is the second-largest tuna fishing ground in the world, accounting for approximately 1.2 million tonnes (23%) of the estimated 5.2 million tonnes of global commercial tuna catch in 2023. This study examined the relationship between tuna catches, specifically skipjack, bigeye, and yellowfin tunas, and prey biomass (Nautical Area Scattering Coefficient, NASC) estimated from acoustic surveys conducted in the southwestern Indian Ocean from 20 April to 15 May 2019. Environmental variables were derived from the Copernicus Ocean Model, and tuna length data from the IOTC. The estimated total tuna catch in the study area was approximately 166,400 tonnes, with the northwestern region showing the highest catches and NASC values. Tuna catches increased with NASC; however, the relationship was non-linear. While skipjack showed no significant correlation with NASC, bigeye and yellowfin tunas exhibited weak but significant positive correlations. Environmental analysis revealed that the northern waters had high surface temperatures, low salinity, and low oxygen levels, with mid and deep layers characterized by low temperature, salinity, oxygen, and chlorophyll. These findings offer a foundation for understanding tuna distribution in relation to prey and environmental conditions, highlighting the need for future species- and fishery-specific studies to support sustainable tuna resource management.

This study aimed to enhance the operational efficiency and safety of offshore eel trap fisheries by developing six types of automated fishing equipment: a bait crusher, bait cutter, main line arranging device, trap cleaning device, eel sorting device, and fish pump system. Sea trials demonstrated that the bait crusher and bait cutter significantly reduced manual labor and processing time while maintaining bait quality. The main line arranging device improved productivity and safety by automating the sorting of looped cords. The trap cleaning device effectively removed fouling organisms using high-pressure water and rotating brushes. The eel sorting device enabled automatic size-based selection, improving resource management and operational efficiency. The fish pump system transferred eels rapidly with minimal physical damage, reducing unloading time by over 80% and decreasing labor requirements. A satisfaction survey of fishery participants confirmed that all developed devices were highly effective in reducing workload, enhancing safety, and improving operational performance. The automated equipment developed in this study is expected to contribute to the sustainable management of offshore eel trap fisheries and to offer potential applicability to other coastal and offshore fisheries.

This study examined the offshore eel trap fishing process using one year of fishing logs and fishermen’s insights to identify key operational challenges and propose equipment improvement for greater efficiency and safety. Conger eel catches varied significantly by season, depth, and temperature, peaking in winter at 85–90 m and 23°C. The western waters of Jeju Island were identified as a major fishing ground, with the highest catch recorded in November and the lowest in July, reflecting seasonal trends. Each fishing operation deployed about 10,000 traps, with an average loss of 38 traps, posing economic concerns. The process involved intensive manual labor in bait preparation, trap retrieval, catch separation, line loading, and unloading, leading to high physical demands and safety risks. To address these issues, the study proposed automation through the development of a line loading device, trap cleaning device, bait processing machine, and automatic catch separator. These innovations could reduce the labor force required by one to two workers per process, alleviate workloads, and enhance resource management. By integrating quantitative logbook analysis with field-based knowledge, this study offers practical value. Further research is recommended on automation development, cost-effectiveness, and field validation to support safer and more sustainable eel trap fisheries.

Aviation safety is critically dependent on effective communication, particularly in the English language, which serves as the international language of aviation. This paper explores the significance of proficient English language communication among aviation professionals and its impact on operational safety. Effective communication in aviation involves various factors such as lack of accent, perfect listening skills, effective hearback and readback procedures, and more. Additionally, English language efficiency in aviation is closely related to emotional stability and the ability to manage stress, both of which are crucial in highpressure environments. The research will also look into the regulatory challenges faced by the aviation industry in standardizing and enforcing language proficiency requirements by the International Civil Aviation Organization and other international institutions. Through a thorough review of existing regulations, industry practices, and case studies, this paper highlights the steps taken to improve communication skills among pilots, air traffic controllers, and other key aviation professionals.

This article critically assesses the role of the International Criminal Court’s (ICC) in enforcing International Humanitarian Law (IHL). The ICC was designed to ensure accountability for severe IHL violations. However, its operational capacity faces significant challenges, particularly its reliance on state cooperation for enforcement and political resistance. This article explores the Court’s jurisdiction, the principle of complementarity, and its investigative processes while analyzing resistance from nonsignatory states such as the US, China, and Russia. The US sanctions against the ICC especially with President Trump’s executive order of February 6, 2025, will exemplify the ongoing tension between state sovereignty and international accountability. Additionally, the article highlights issues within the Rome Statute, including ambiguities regarding state cooperation, jurisdiction, and immunity, which affect the Court’s efficacy. Despite some successes in prosecuting high-profile leaders, the ICC’s credibility remains a matter of debate due to its limited enforcement, inconsistent state support, and continued political resistance.

Recent global efforts to combat climate change have accelerated, with nations adopting carbon strategies such as carbon taxes and emission trading system (ETS) to support their net-zero commitments. These initiatives enable governments to enforce mitigation while maintaining their dual goal of fostering economic growth. Vietnam, a developing country, has emerged as a proactive participant by launching a national ETS, drawing from international best practices and domestic geographical advantages. This article examines the process and challenges involved in designing and implementing an ETS in Vietnam, exploring the necessary policy frameworks, institutional structures, and market mechanisms. It highlights key considerations such as the selection of sectors and entities to be covered, the allocation of emission allowances, and the establishment of new market management solutions. This article concludes with strategic recommendations to support the development of a successful and sustainable ETS mechanism in developing country like Vietnam.
