In particular, the confidence of U.S. businesses rose particularly strongly, up 46% from 1%. In Japan and Europe, but confidence has improved, but the business is still quite pessimistic, with a score of -53% for trust business in the land of the rising sun and -4% for the companies in "old continent".

However, if compared to same period last year, we can see, business confidence in the G7 group of countries has been much reduced, with a decrease of 11 percentage points compared to the precious time of 1/2011.

In the group of countries in Asia-Pacific survey of business confidence rose 11 percentage points, up to 2% in Q1 this year from 9% in Q4 last year.

Vietnam is among the countries, but in contrast to the increase in business confidence score of the group, the confidence of businesses in Vietnam back in the direction of movement decreased.

In a recent quarter, the index of business confidence in Vietnam only 6%, from 34% in Q4 last year, equivalent to 28 percentage point reduction. In contrast, in Thailand, the country is in the process of recovery from the flood history, business confidence index rose to 8% -52% from the fourth quarter.

"Happily, the prospect of many businesses has increased over the past 3 months. However, prospects for global growth is still quite fragile. Compared to last year can see, the past 12 months how that difficult for businesses, and they are still extra effort, "said Ed Nusbaum, CEO of Grant Thornton International, said .

The faith prospered in business in the G7 has raised the confidence of global business in the IBR report up 19% in Q1, from 0% in the previous quarter.

The developing economies also saw an improvement in business confidence. In the BRIC group (including four large emerging economies especially Brazil, Russia, India and mainland China), the average increased to 41% from 34% in ASEAN, the index increased to 27% from 0% and in Latin America, the index increased from 61% to 73%.

"Signal recovery in the developed economies are clearly positive impact to the emerging economies. The BRIC economies such as Mexico and Turkey are playing an increasingly important role in global growth prospects. But when the economy is further integrated into the global economy, where businesses have become more dependent on the health of the economy grow, "commented Mr. Nusbaum.

Particularly for the case of Vietnam, Mr Ken Atkinson, Director of Grant Thornton Vietnam, said that the activities supported loans, financing costs, the shortage of skilled labor, access to finance and the bureaucracy continues to be major barriers to improving business confidence in Vietnam.

 "It's not happy to see the trend of business confidence in Vietnam is not the same way with the improvement of the world. However, the policies of the Government of Vietnam seems to be effective, reflecting the slowdown effect of inflation and trade deficit with the stability of exchange rates. Along with the decline of interest rates, these factors may help improve business confidence in the 2nd quarter and next time, "Mr Atkinson said.
