The outgoing government of caretaker Prime Minister Paolo Gentiloni forecasts economic growth of 1.5 percent in 2018, in line with last year's rate which was the strongest since 2010.
The Markit/Nikkei Japan Services Purchasing Managers Index (PMI) rose to 52.5 in April on a seasonally adjusted basis from 50.9 in March.
China's manufacturing sector showed a further marginal improvement in operating conditions last month, driven by accelerated output, although weaker demand in worldwide markets stagnated exports, according to an unofficial leading economic indicator released on Wednesday.
Inflationary pressures moderated for the second month in a row, with the softest increases for input costs and output charges reported since September 2017 and July 2017, respectively, the survey said.
The increase in new business was the first recorded by the survey so far in 2018. It also marks the 21st straight month of expanding business conditions in China, reports Chinese news portal China Economic.
While India's retail inflation has eased this year and hit a five-month low of 4.28 percent in March it remained above the Reserve Bank of India's (RBI) medium-term target of 4 percent.
Output fell to its lowest since November at 53.9 from 55.0 in March, a decline which survey respondents partly attributed to capacity constraints and supply chain disruption, IHS Markit said.
"The manufacturing sector saw growth weaken further at the start of the second quarter, but let's not lose sight of the fact that the overall pace of expansion remains encouragingly solid". The rate of growth in output was solid overall and the fastest since January.
While the headline index improved over the month, IHS Markit said the details of the report were less impressive. The rate of input price inflation also was shown to have accelerated to the sharpest in nearly seven years. In some cases, construction firms noted that a knock-on impact from unusually bad weather conditions had contributed to delays with sales completions during the latest survey period.
"Uncertainty has also intensified due to worries regarding trade wars and Brexit, underscoring downside risks to the outlook", he added. Problematically, the rate of contraction quickened the fastest in just over a year.
