China’s top policy makers said they plan prudent and neutral monetary policy and proactive fiscal policy next year as they seek to sustain a steady expansion with room for reforms. Preventing and controlling financial risk to avoid asset bubbles will be a priority, along with deepening supply-side structural reform, according to a statement Friday from the official Xinhua News Agency issued after officials concluded the three-day Central Economic Work Conference in Beijing. Policy makers said they aim to ensure currency and liquidity levels are both kept basically stable. Optimism over the growth outlook has been increasing even as the People’s Bank of China shifts toward selective tightening after more than a year of record-low interest rates. Forecasts for full-year 2017 growth have climbed to 6.4% from 6.3% since September, a Bloomberg survey showed Friday.
