Chinese markets dip as Communist Party mulling over indefinite term for Xi Jinping

China's major stock indices fell on Tuesday morning, led lower by real estate and resource firms, as investors booked profits after a six-session winning streak.

Market participants continued to weigh the impact of certain amendments in the wording of China's constitution.

China's ruling Communist Party on Sunday set the stage for President Xi Jinping to stay in office indefinitely, with a proposal to remove a constitutional clause limiting presidential service to just two terms in office.

"President Xi Jinping will not tolerate the slowdown associated with rebalancing to tarnish his name as he builds a case to justify a third term in power," Eaton added.

Anbang Insurance Group Co Ltd said on Monday it fully supported the Chinese insurance regulator's decision to temporarily take control of the company, and remains committed to the development of its overseas subsidiaries.

The Chinese government's action on Anbang, along with the announcement that its chairman was being prosecuted for economic crimes, dramatically illustrated Beijing's willingness to curtail big-spending conglomerates as it cracks down on financial risk.
