There is another related sense in which China’s emergence is bound to change the international system as we know it. The European nation-states that constituted the original founding core of the international system were all, roughly speaking, of a similar kind: namely, in global terms, small to medium sized. Following the Second World War, the number and diversity of nation-states was dramatically transformed as a result of decolonization (and then again after 1989 with the break-up of the USSR). The second half of the twentieth century was dominated by the US and the USSR, which were both far larger than even the biggest European nation-states. Partly as a result, the West European states were encouraged to combine their power in what we now know as the European Union, a grouping of nation-states. It has become common to see such unions of nation-states as the way forward, ASEAN and Mercosur (a regional trade agreement between four South American countries) being further examples, though neither as yet involves any pooling of sovereignty. The American perspective, for obvious reasons, has invariably placed the major emphasis on the nation-state. But the rise of China and India threatens to transform the picture again. In one sense, of course, it marks the reassertion of the nation-state. These are no ordinary nation-states, however, but states on a gargantuan scale. If this century will increasingly belong to China and India, in conjunction with the United States, then it should also be seen as the Age of the Megastate. [700] This does not mean that unions of nation-states will go out of fashion, but their primary
Quite where this will leave the old Westphalian system is difficult to say. States of the scale, size and potential power of China and India will dwarf the vast majority of other countries. This will not be an entirely new phenomenon. During the Cold War, the United States and the Soviet Union both established unequal relations with their subordinate allies to an extent which frequently undermined or greatly detracted from the sovereignty of the latter. This is the case, in varying degrees, of the US ’s present relationship with many countries. But China and India are on a different scale even to the United States: China has more than three times the population and between them India and China comprise around 38 per cent of the world’s population. As both are still only at the earliest stages of their transformation, it is impossible at present to conceive what this might mean in terms of their relationship with other states. The Westphalian system may well survive the emergence of China and India as global powers, but it will certainly look very different from any previous stage in its history.
There is one other aspect of China’s emergence as a global power that is also novel. Hitherto, ever since the onset of industrialization in the late eighteenth century, the most powerful countries in the world have shared two characteristics. First, they have enjoyed one of the highest (if not the highest) GDPs of their time. Second, they have also had an extremely high GDP per head: the richest nations have also had the richest populations. That was true – in rough chronological order – of Britain, France, Germany, the United States and Japan. The only exception, arguably, was the USSR. That situation is about to change: China will share only one of these characteristics, not both. It already has a high GDP – the third highest in the world measured by market exchange rates. But even when it overtakes the United States in 2027, as predicted by Goldman Sachs, it will still have a relatively low GDP per head, and even in 2050 it will still only belong to the ‘upper middle group’ rather than the ‘rich club’ (see Figure 23). Welcome to a new kind of global power, which is, at one and the same time, both a developed – by virtue of the size of its GDP –
