BEIJING - China's economy must open wider to the outside world to add fuel to national growth, Chinese President Xi Jinping told the body in charge of steering the country's reform on Tuesday.

"China should make unswerving efforts to attract foreign investment and foreign technology, and improve the mechanism for the country's opening up," he said at the 16th meeting of the Central Leading Group for Deepening Overall Reform.

Promoting opening up while pushing forward reforms will add new impetus and vitality and provide new room for economic growth, Xi said.

The leading group adopted a series of guidelines covering subjects including a negative list approach to regulating market access, relaxed border control policies, encouraging state-owned enterprises to absorb private capital and granting permanent residence permits to foreigners.
