China growth must be at least 6.5%, says President Xi Jinping
President Xi Jinping has said that China needs at least 6.5% economic growth in coming years to become "moderately prosperous".
The ruling Communist Party also announced plans to let the country's tightly-controlled currency trade freely by 2020.
The announcements follow a high-level planning meeting last week at which party leaders promised to make the world's second-largest economy more productive and to raise living standards.
Mr Xi said growth of "no less than 6.5%" is required to achieve the party's goal of doubling the economy's size by 2020 from its 2010 level, the official Xinhua News Agency said.
Chinese growth has slowed steadily over the past five years as the ruling party tried to steer the economy to a more sustainable expansion based on domestic consumption instead of trade and investment.
An abrupt decline over the past year prompted Beijing to try to shore up growth by cutting interest rates six times since last November.
Mr Xi's comment was the latest indication the party might reduce its official growth target, which has stood at 7% since 2011. Last year's economic growth was 7.4% and this year it is expected at just below 7%.
Private sector analysts have warned sticking to a high target could conflict with official efforts to shift China to more sustainable growth based on domestic consumption instead of trade and investment.
Some say a more realistic level would be 5.5 to 6%, which would still rank China among the fastest-growing major countries.
Mr Xi said "maintaining a medium-high level of growth" was required for "comprehensively building a moderately prosperous society", according to Xinhua. China's GDP per head is about 8,000 US dollars (£5,190) compared with 55,000 dollars (£35,600) for the US and 36,000 dollars (£23,300) in Japan.
Last week, the ruling party eased its birth limits to allow all couples to have two children in a response to the need for more young workers in a rapidly ageing society.
On Tuesday, the party also said its leaders agreed last week to make the yuan a "freely tradable and freely usable currency" by the end of their next five-year development plan in 2020.
The United States and other governments have pressed Beijing for years to end controls they complained kept the yuan undervalued, giving Chinese exporters an unfair price advantage. Some American politicians had demanded punitive tariffs on Chinese goods in retaliation.
Beijing has been gradually expanding use of the yuan abroad for trade but restricts the daily movement of its exchange rate and the flow of money into and out of China.
Chinese leaders have said for years they eventually would allow the yuan to be freely traded. But they said that would require extensive reforms to China's state-run financial system to make banks and other entities capable of coping with more abrupt changes in interest rates and financial flows that might result from that.
Tuesday's one-sentence party statement gave no indication what changes in currency regulation were to come or when.
The announcement comes at a time when analysts say market forces are putting downward pressure on the yuan. That could mean a loosening of controls would cause the currency to weaken, making the decision more politically acceptable domestically by reducing the price of Chinese exports and helping exporters who are struggling with weak global demand.
At the same time, the party plans to switch to a "negative list" in regulating foreign exchange, the statement said. That would allow companies to do whatever is not explicitly prohibited, instead of only what regulators say is allowed.
The party said it also would promote the yuan's addition to the basket of currencies used by the International Monetary Fund to determine the value of its in-house currency, known as Special Drawing Rights. Gaining a place alongside the dollar, euro, yen and British pound would be a political trophy reflecting China's growing financial importance.
Beijing rattled global markets on August 11 with a surprise change in its exchange rate mechanism to make the yuan more market-oriented.
That resulted in the yuan falling by 2%, which prompted suggestions it was devaluing the currency to help struggling Chinese exporters.
