The People's Republic of China and her relations with the countries of the association of Southeast Asian nations : 1969-1975

Phe Ihesis examines the evolution of the -policies of the People fs Jtenublie of China towards J?hail°nd, PTal ysia, Singapore, Iidonesia pad the Philip-pines, organised in the Association of Southeast Asian Nations from 1969 to 1975• 2ze first central point of this study is an *ir sumption that the foreign relations of The People's Tepublic of Chi la Towards Southeast ^sia have been motivated by a dynamic interplay of t^o main factors: (1) Farxist-Leninist ideology and ICao J^e-tung Ph^ught, which dictate to China to behave as a revolutionary Dover vhich must assist the insurgent movements in the area in their strug fle to overthrow the local governments; (2) national interest, vhich demands of China to safeguard the southern flank of her territory bordering on Southerst 'sia through Friendly relations, trade and ot*»er conventional inrtniments of diplomacy. hile the tvo main motive factors are nuTually antagonistic and exclusivet the Chinere leaders are nevertheless at te mi ting to oring them iirco a coherent policy under Mao's theory of tve {hniity of op-nosites," vhich believes that it is -possible to reconcile these co-posing tendencies into a dynamic enuibrium through vhich both opnosites could be promoted at the same time although not to the same extent* la other words, the Chinese leaders conceive the dynamic equilibrium as a continuum between them in a mix in which one or the other orientation predominates in different •periods* Bins we might see China1 s conduct motivated in one period by mostly ideological considerations at the expense of the staire-to-state relations, then ve might see her policy in the middle of the continuum and suf ering from immo bill sine and just muddling through, or finally ?fe might see her emphasising friendly ties at the expense of support of revolutionary movements at the other extreme -point of the spectrum* !fhe mechanism vhich enables Peking to move from one pole to the other of the spectrum is activated by the following elementsJ (1) the result of an internal power struggle within the leadership in Peking between ideologically radical and moderate elements, which enables the victorious faction to initiate nev policies; (2) Peking's assessment of the changing intentions and capabilities of the major powers in the area; (3) internal changes within the countries of the area and the changing attitudes of their governments towards China; (4) changing fortunes of revolutionary movements operating in the area* 'Phe second major point of this study is an assertion that while China's conduct toward Southeast *lsia after her foundation in 1949 was primarily based upon ideological considerations, the beginning of the seventies saw the national interest reasserting itself as the leading motive factor* Thus China talks with her neighbours in Southeast asia in terms of relevance of fllong historical ties," casting herself into the role of a benevolent "older brother11 who is entitled to reopect and deference in exchange for patronage and protection* Hence the traditional echoes of the past are emerging ever stronger and influencing her postures towards the region, while the open support to revolutionary moevments is underplayed at the moment.

Overview: oxidant and particle photochemical processes above a south-east Asian tropical rain forest (the OP3 project); introduction, rationale, location, characteristics and tools

In April–July 2008, intensive measurements were made of atmospheric composition and chemistry in Sabah, Malaysia, as part of the "Oxidant and particle photochemical processes above a South-East Asian tropical rainforest" (OP3) project. Fluxes and concentrations of trace gases and particles were made from and above the rainforest canopy at the Bukit Atur Global Atmosphere Watch station and at the nearby Sabahmas oil palm plantation, using both ground-based and airborne measurements. Here, the measurement and modelling strategies used, the characteristics of the sites and an overview of data obtained are described. Composition measurements show that the rainforest site was not significantly impacted by anthropogenic pollution, and this is confirmed by satellite retrievals of NO2 and HCHO. The dominant modulators of atmospheric chemistry at the rainforest site were therefore emissions of BVOCs and soil emissions of reactive nitrogen oxides. At the observed BVOC:NOx volume mixing ratio (~100 pptv/pptv), current chemical models suggest that daytime maximum OH concentrations should be ca. 105 radicals cm−3, but observed OH concentrations were an order of magnitude greater than this. We confirm, therefore, previous measurements that suggest that an unexplained source of OH must exist above tropical rainforest and we continue to interrogate the data to find explanations for this.

Neoproterozoic to middle Palaeozoic evolution of the Central Asian Orogenic Belt in south-central Mongolia: chronological and geochemical perspectives

Mongolia occupies a central position within the eastern branch of the large accretionary Central Asian Orogenic Belt (CAOB) or Altaids. The present work aims to outline the geodynamic environment and possible evolution of this part of the eastern CAOB, predominantly from the Cambrian to the middle Palaeozoic. The investigation primarily focussed on zircon geochronology as well as whole-rock geochemical and Sm–Nd isotopic analyses for a variety of metaigneous rocks from the southern Hangay and Gobi-Altai regions in south-central Mongolia. The southern slope of the Hangay Mountains in central Mongolia exposes a large NWSE-trending middle Neoproterozoic ophiolitic complex (c. 650 Ma), which is tectonically integrated within an accretionary complex developed between the Precambrian Baydrag and Hangay crustal blocks. Formation of the entire accretionary system along the north-eastern margin of the Baydrag block mainly occurred during the early Cambrian, but convergence within this orogenic zone continued until the early Ordovician, because of on-going southward subduction-accretion of the Baydrag block. An important discovery is the identification of a late Mesoproterozoic to early Neoproterozoic belt within the northern Gobi-Altai that was reworked during the late Cambrian and throughout the late Ordovician/Devonian. Early Silurian low-grade mafic and felsic metavolcanic rocks from the northern Gobi-Altai display subduction-related geochemical features and highly heterogeneous Nd isotopic compositions, which suggest an origin at a mature active continental margin. Early Devonian protoliths of granodioritic and mafic gneisses from the southern Gobi-Altai display geochemical and Nd isotopic compositions compatible with derivation and evolution from predominantly juvenile crustal and mantel sources and these rocks may have been emplaced within the outboard portion of the late Ordovician/early Silurian active continental margin. Moreover, middle Devonian low-grade metavolcanic rocks from the southwestern Gobi-Altai yielded geochemical and Nd isotopic data consistent with emplacement in a transitional arc-backarc setting. The combined U–Pb zircon ages and geochemical data obtained from the Gobi-Altai region suggest that magmatism across an active continental margin migrated oceanwards through time by way of subduction zone retreat throughout the Devonian. Progressive extension of the continental margin was associated with the opening of a backarc basin and culminated in the late Devonian with the formation of a Japan-type arc front facing a southward open oceanic realm (present-day coordinates).

The role of indigenous people in national development processes: Participation and marginalisation of indigenous Bedouin in South Sinai tourism development

The Bedouin of South Sinai have been significantly affected by the politics of external powers for a long time. However, never had the interest of external powers in Sinai been so strong as since the Israeli-Egyptian wars in the second half of the 20th century when Bedouin interests started to collide with Egypt’s plans for a development of luxury tourism in South Sinai. rnrnThe tourism boom that has started in the 1980s has brought economic and infrastructure development to the Bedouin and tourism has become the most important source of income for the Bedouin. However, while the absolute increase of tourists to Sinai has trickled down to the Bedouin to some extent, the participation of Bedouin in the overall tourism development is under-proportionate. Moreover, the Bedouin have become increasingly dependent on monetary income and consequently from tourism as the only significant source of income while at the same time they have lost much of their land as well as their self-determination.rnrnIn this context, the Bedouin livelihoods have become very vulnerable due to repeated depressions in the tourism industry as well as marginalization. Major marginalization processes the Bedouin are facing are the loss of land, barriers to market entry, especially increasingly strict rules and regulations in the tourism industry, as well as discrimination by the authorities. Social differentiation and Bedouin preferences are identified as further factors in Bedouin marginalization.rnrnThe strategies Bedouin have developed in response to all these problems are coping strategies, which try to deal with the present problem at the individual level. Basically no strategies have been developed at the collective level that would aim to actively shape the Bedouin’s present and future. Collective action has been hampered by a variety of factors, such as the speed of the developments, the distribution of power or the decay of tribal structures.rnWhile some Bedouin might be able to continue their tourism activities, a large number of informal jobs will not be feasible anymore. The majority of the previously mostly self-employed Bedouin will probably be forced to work as day-laborers who will have lost much of their pride, dignity, sovereignty and freedom. Moreover, with a return to subsistence being impossible for the majority of the Bedouin, it is likely that an increasing number of marginalized Bedouin will turn to illegal income generating activities such as smuggling or drug cultivation. This in turn will lead to further repression and discrimination and could escalate in a serious violent conflict between the Bedouin and the government.rnrnDevelopment plans and projects should address the general lack of civil rights, local participation and protection of minorities in Egypt and promote Bedouin community development and the consideration of Bedouin interests in tourism development.rnrnWether the political upheavals and the resignation of president Mubarak at the beginning of 2011 will have a positive effect on the situation of the Bedouin remains to be seen.rn
