Developing countries and advanced economies differ greatly in their level of "skepticism" towards international trade and foreign investment, a study of people across 44 countries revealed Tuesday.

A median of 81 percent of those surveyed believed that international trade and global business ties were good things, according to a study by the U.S.-based Pew Research Center.

The United States is likely to remain the world's largest market for diamonds for the next 15 years despite a growing appetite for the gems from China and India, leading producer De Beers said Wednesday.

China has the fastest growing demand, jumping to a share of about 15 percent of the world's diamond market from less than three percent in 2003.

Bureaucracy, a lack of competition and a banking system in ruins have ossified the Tunisian economic model, the World Bank said Wednesday, calling for sweeping reforms.

Poverty and soaring unemployment were behind the 2011 uprising when Tunisians overthrew longtime dictator Zine El Abidine Ben Ali.

Britain's 12-month inflation dipped to 1.5 percent in August from 1.6 percent in July, official data showed on Tuesday, easing pressure on the Bank of England to raise rates.

The Consumer Prices Index (CPI) inflation measure matched May's level, which had been a near five-year low point.

South Korea's finance minister said Tuesday that "alarm bells" were ringing over Asia's fourth largest economy, and warned of the sort of protracted slowdown that hit Japan in the 1990s.

The Argentine economy will grow 2.8 percent in 2015, the government said Monday, despite the recession gripping the country.

China's outbound investment more than doubled in August to $12.62 billion, data showed Tuesday, far outstripping foreign direct investment (FDI) into the country, which fell to a four-year low.

China has been actively acquiring foreign assets, particularly energy and resources, to power its economy, with firms encouraged to "go out" and make overseas acquisitions to gain market access and international experience. Officials have said overseas direct investment (ODI) could exceed FDI this year.

Ukrainian President Petro Poroshenko faces a strong backlash from some of his staunchest supporters for bowing to Russian pressure and postponing the implementation of an EU trade pact which is due to be ratified Tuesday.

Several of them have warned the decision to delay the ex-Soviet state's economic tilt westward could spark a repeat of the EuroMaidan protests that toppled Kremlin-backed Viktor Yanukovych earlier this year, after he rejected the same deal.

China's central bank said Monday it had approved state-owned Bank of China, one of the nation's four biggest lenders, to be its designated yuan currency clearing house in Paris.

In June, China and France signed an agreement for yuan clearing arrangements, one of a number of such accords Beijing has sought with foreign countries to help boost use of its currency overseas.

The Russian ruble fell on Monday to a historic low against the dollar after the West imposed fresh sanctions over Ukraine.
