The growing gulf between rich and poor in China is certainly something that worries China's leaders. In their 10 years in power, Hu Jintao and Wen Jiabao pledged they would create a "harmonious society". Instead inequality has risen - the World Bank says China is among the most unequal countries in Asia.
China's leaders have been responding. By slowing growth down to less than 8% a year and trying to "rebalance" the economy towards service industries and consumer spending they hope to create more jobs and encourage spending. They have called for minimum wages to rise by more than 10% a year until 2015. They say they have almost completed a national pension scheme covering all rural areas for the first time.
China's leaders are used to presiding over an economy that has been the envy of the world. But Premier Wen Jiabao gave his key address to senior business figures at the World Economic Forum in Tianjin against the backdrop of some of the worst economic news China has seen in years.
Weak demand in Europe and America is hitting exports, while China's own domestic economy appears to be slowing fast too. It all means that growth this year will fall to around seven percent, the lowest in two decades.
China is the world's second biggest economy, its rising superpower, and is on the cusp of a once-in-a-decade leadership change, but the man expected to take over at the head of the Communist Party has vanished from view, and we don't know why.
Is Xi Jinping sick? Has he had a mild heart attack? Did he hurt his back playing football or swimming? Is he extraordinarily busy preparing for the day, probably next month, when he will be elevated to take over from Hu Jintao as the head of China's Communist Party, or is there some more sinister power struggle happening?
China's leaders are facing a conundrum. They're preparing to hand over power to a new generation in the autumn.
But look at all the data rolling in and it seems the current Communist leadership could be stepping aside just as China's economy is at its lowest ebb in years. So should they try to give things a boost, or will that make any problems they pass on to the new leadership worse?
The moment Liu Xiang crashed out of the 110m hurdles was, for millions of Chinese television viewers, one of the most dramatic, heart-rending moments of the London Olympics.
But now many have been left feeling duped after it emerged that almost everyone, except for the television audience, knew Liu, China's great hope on the track, was injured and unlikely to have a chance of wining gold.
Is China becoming Africa's new colonial master? Is Beijing sucking away resources to drive its own economic growth, while offering little in return?
Or is such talk the product of fear and envy? Is it a sign of Western anxieties, that China is fast becoming the new power in Africa, building more equal relationships, and undermining Western influence on the continent?
China's space programme is preparing to make its own small piece of history by putting its first female astronaut into space, and China's internet has been buzzing with talk of some unusual selection criteria.
At a launch site in the desert the Shenzhou-9 spacecraft is being readied. It may blast off this weekend, and one of the three crew is likely to be a woman.
As the deadline for foreign combat troops to leave Afghanistan gets closer, the possibility of growing instability is a serious concern for its neighbours and the major regional powers of China and Russia.
In an interview for a Chinese newspaper President Hu Jintao said the SCO member countries will seek a larger role in Afghanistan's reconstruction.
China has detained political activists and placed others under increased surveillance in cities around the country to prevent them from marking the anniversary of the massacre in Tiananmen Square on Monday.
Hundreds died when the Communist Party used the army to crush pro-democracy protests in 1989. On Sunday, the US called on China to stop harassing those who took part in the Tiananmen protests and their families.
