China Caixin manufacturing PMI contracts in April

``Activity in China's manufacturing sector unexpectedly declined further in April, a private survey showed Tuesday, reviving doubts over the health of the world's second-largest economy. The Caixin Manufacturing Purchasing Managers' Index (PMI) fell to 49.4 in April from 49.7 in March, according to Markit, which compiles the index.
