【正文】 one of the biggest and most highpowered delegations a british prime minister has ever led to china.　　just think about some of the prizes that the rise of china could help to bring within our grasp.　　strong, and sustainable growth for the global economy.　　vital progress on the doha trade round which could add $170 billion to the global economy.　　a real chance to get back on track towards a legally binding deal on emissionsunprecedented progress in tackling poverty.　　china has lifted 500 million people out of poverty in just thirty years.　　although there is still a long way to go – that’s more people lifted out of poverty than at any time in human history.　　you can see the results right across this enormous country.　　when i worked in hong kong briefly in 1985, shenzhen was barely more than a small town, surrounded by paddy fields and waterways.　　today it is a city larger than london. it makes most of the world’s ipods and one in ten of its mobile phones.　　and there are other benefits too in tackling the world’s most intractable problems.　　i wele the fact, for example, that more than 900 chinese doctors now work in african countries and that in uganda it is a chinese pharmaceutical firm that is introducing a new antimalarial drug.so i want to make the positive case　　for the world to see china’s rise as an opportunity not a threat.　　but china needs to help us to make that argument　　to demonstrate that as your economy grows, so do our shared interests, and our shared responsibilities.　　　　we share an interest in china’s integration into the world economy, which is essential for china’s development.　　if we are to maintain europe’s openness to china, we must be able to show that china is open to europe.　　so we share an interest in an international system governed by rules and norms.　　we share an interest in effective cooperative governance, including for the world economy.　　we share an interest in fighting protectionism　　and in a coordinated rebalancing between surplus and deficit countries.　　these interests, those responsibilities are both economic and political.　　let me take each in turn.　　economic responsibilities　　first, economic responsibilities.　　let’s get straight to the point.　　the world economy has begun to grow again after the crisis.　　but that growth is very uneven.　　led by china, asia and other emerging markets are growing quickly.　　but in much of the advanced world growth is slow and fragile and unemployment stubbornly high.　　we should not be surprised at this.　　the crisis has damaged many advanced economies and weakened their financial sectors.　　they face major structural and fiscal adjustments to rebalance their economies.　　this is true of my own country.　　we know what steps we need to take to restore the public finances and rebalance our economy towards greater saving and investment and greater exports.　　and we have begun to take them.　　but for the world economy to be able to grow strongly again – and to grow without creating the dangerous economic and financial instabilities that led to the cri
