A new survey indicated that China's manufacturing activity turned back into expansion-mode in June 2017 (from contraction in the preceding month). In fact, manufacturing activity in China expanded at the fastest pace in three months. This somewhat eases market participants' concern about the Chinese economy and therefore supported the performance of stocks across the Asian continent on Monday.

Meanwhile, Indonesia's core inflation (which excludes administered and volatile food prices) eased to 3.13 percent year-on-year (y/y) in June 2017, from 3.20 percent (y/y) in May. Headline inflation, however, slightly rose to 4.37 percent (y/y) in June, from 4.33 percent (y/y) in the preceding month. The latter remains high due to the government's electricity tariff reforms.
