Although not unexpected, the Soviet invasion of Afghanistan was still largely a shock to the West. It was the first time since the Second World War that the Soviets had directly intervened in a country outside the Warsaw Pact. Despite the intervention eventually being seen as Moscow's ‘Vietnam’ the West was initially unsure about what the invasion meant for stability in the region or the future conduct of East–West relations. In response to the crisis the UK Foreign & Commonwealth Office (FCO) proposed that Afghanistan revert to a neutral and non-aligned status in an attempt to create the basis for a viable political settlement, one that would allow the Soviet Union to withdraw troops without losing face. It launched the proposal in early 1980, lobbying other countries to support and champion the idea, culminating in a visit to Moscow by the Foreign Secretary, Lord Carrington, in July 1981. In this early phase of Soviet intervention the British proposals were premature but not without merit. They anticipated the strategy the Soviets would eventually adopt in their attempt to achieve an orderly withdrawal.  相似文献

The cross-border flows of goods, investment, services, know-how and people associated with international production networks–call it ‘supply-chain trade’ for short–has transformed the world. The WTO has not kept pace. This paper argues that adapting world trade governance to the realities of supply-chain trade will require a new organization–a WTO 2.0 as it were. Reasoning on the optimal nature of the new organization is based on the nature of supply-chain trade, the nature of the disciplines that underpin it, and the nature of the gains from cooperation.  相似文献

The behavior of academic researchers who engage in cooperation with industrial partners has already been the subject of considerable research. A lack of understanding exists regarding the motivations of scientific research groups to engage in cooperation with other types of external non-academic organizations and the perceived barriers that may inhibit this activity. In this paper we analyse the motivations and perceptions of risks that shape scientific research groups’ cooperation with industry and government partners. We find that motivations to cooperate are partly dependent on the type of partner organization involved, with advancing research goals mainly acting as an inducement to cooperate with government agencies, while searching for opportunities to apply knowledge motivates partnerships with firms. We also find that the majority of research groups cooperate with both firms and government, with their major motivation being to apply their knowledge. Among research groups that only cooperate with firms, interaction effects between motivations influence the likelihood of cooperation. Research groups do not consider risk to scientific autonomy a barrier to cooperating with firms, while risk to scientific credibility inhibits cooperation independently of the type of external partner. However, being motivated to advance research can reduce the effect of perceived barriers, independent of the type of partner organisation.  相似文献

This article offers an assessment of cross-Strait relations almost 30 months into the Ma Ying-jeou administration, and two years before Hu Jintao likely will begin to give up the titles that make him China's paramount leader. The article briefly describes the essential character of cross-Strait relations before President Ma came to office; reviews what has happened during his administration; clarifies what this process represents; examines what might happen in the future, and concludes with implications for other countries— particularly the United States.  相似文献
