A factory slump in Asia's two biggest exporters China and Japan deepened in June as crumbling orders from abroad dragged activity to seven-month lows, heightening worries that the health of the global economy is deteriorating. 

PMI reports on major exporters South Korea and Taiwan also indicated new orders from overseas were falling. The manufacturing sectors in these countries contracted in June for the first time in five months, the reports showed.

In India, where the economy is more reliant on domestic activity, the factory sector picked up in June. But its new export orders growth was the weakest in seven months.
