Fitch Ratings in Chinese debt downgrade

China has just seen its credit rating cut by Fitch due to rising debt concerns. Fitch has cut China's long-term local currency rating to A+ from AA-.

The downgrade only applies to China's yuan-denominated debt, which is mainly traded domestically.

The BBC spoke with Shane Oliver, head of investment strategy and chief economist with AMP Capital Investors. He explains whether investors should be concerned about Fitch's move.
