China and Southeast Asia

In the new millennium, no issue in international relations will be more important than how to accommodate the rising power of China. Many analysts, especially in the United States, see China as a significant threat to American interests in Asia. Washington has treaty commitments in both Northeast and Southeast Asia and retains a substantial military presence in the region. Beijing claims it does not seek to replace the United States reigning global hegemony, but seeks to promote a multi-polar world in which six states (the US, China, the EU, Russia, Japan, and India) would have pre-eminent status.

US hegemony and Southeast Asia - The impact of, and limits to, US power and influence

The United States has exerted a major influence on Southeast Asia, especially since World War II. As both a promoter of neoliberal reform and as the key strategic actor in the wider East Asian region, the impact of U.S. power has been immense. But both the Asian economic crisis and its aftermath, and the more recent war on terror, have highlighted the contradictory impact of evolving U.S. foreign policy and intervention in the region. At both an elite and a mass level there is evidence of resentment about, and hostility toward, U.S. policy and its perceived negative effects. This article outlines how U.S. foreign policy has impacted the region in the economic, political, and security spheres, and argues that not only has it frequently not achieved its goals, but it may in fact be undermining both America's long-term hegemonic position in the region and any prospects for political liberalization.

Rethinking regionalism: Europe and East Asia in comparative historical perspective

Regionally based processes of political and economic integration, security co-operation, and even social identification have become increasingly important and prominent parts of the international system. Nowhere have such processes gone further than in Western Europe. Somewhat surprisingly, similar patterns of regional integration have been steadily developing in East Asia - a region many observers consider unlikely to replicate the European experience. This paper uses an historically grounded comparative approach to examine the historical preconditions that underpinned the formation of the European Union, and then contrasts them with the situation in East Asia today. While the overall geopolitical and specific national contexts are very different, such an analysis highlights surprising similarities and differences, particularly in the role played by the United States in both periods. A comparative analysis allows us to understand and rethink the incentives for, and constraints on, regional integrative processes.

Improving drought tolerance in rainfed lowland rice: An example from Thailand

A large portion of the world's poor farm in rainfed systems where the water supply is unpredictable and droughts are common. In Thailand there are approximately 6.2 million ha of rain fed lowland rice, which account for 67% of the country's total rice-growing area. This rice system is often characterised by too much and too little water in the same season. Farmers' estimates of their annual losses to drought are as high as 45% in the upper parts of the toposequence. In contrast to irrigated rice systems, gains from crop improvement of rainfed rice have been modest, in part because there has been little effort to breed and select for drought tolerance for the target rainfed environments. The crop improvement strategy being used in Thailand considers three mechanisms that influence yield in the drought prone targets: yield potential as an important mechanism for mild drought (where yield loss is less than 50%), drought escape (appropriate phenology) and drought tolerance traits of leaf water potential, sterility, flower delay and drought response index for more severe drought conditions. Genotypes are exposed to managed drought environments for selection of drought tolerant genotypes. A marker assisted selection (MAS) scheme has been developed and applied for selection of progenies in the backcrossing program. The plant breeding program uses rapid generation advance techniques that enable early yield testing in the target population of environments (TPE) through inter-station (multi-location yield testing) and on-farm trials. A farmer participatory approach has been used to identify the TPE for the breeding program. Four terrace paddy levels have been identified, upper (drought), middle (drought prone to favorable) and lower (flooded). This paper reports the change in the breeding program for the drought prone tainted lowland rice environments of North and Northeast Thailand by incorporating our knowledge on adaptation and on response of rice to drought.

Host age effect and expression of cytoplasmic incompatibility in field populations of Wolbachia-superinfected Aedes albopictus

The Asian tiger mosquito, Aedes albopictus (Skuse), is a known vector of dengue in South America and Southeast Asia. It is naturally superinfected with two strains of Wolbachia endosymbiont that are able to induce cytoplasmic incompatibility (CI). In this paper, we report the strength of CI expression in crosses involving field-caught males. CI expression was found to be very strong in all crosses between field males and laboratory-reared uninfected or wAlbA infected young females. In addition, crossing experiments with laboratory colonies showed that aged super- infected males could express strong CI when mated with young uninfected or wAlbA infected females. These results provide additional evidence that the CI properties of Wolbachia infecting Aedes albopictus are well suited for applied strategies that seek to utilise Wolbachia for host population modification.
