The anti-corruption watchdog Transparency International has praised the high standards in business practice maintained by Indian firms in a survey of multinationals from emerging markets.
China received the lowest rating of the five economies whose companies made up three quarters of the total sample in the survey of 100 of the fastest-growing multinationals in 16 emerging economies.
Marked on how transparently they present measures to combat corruption, how they report on their organisations and how they disclose data like revenue, expenditure and taxes, three quarters of the companies scored less than five out of 10.
"As emerging market companies expand their influence they should seize the opportunity to play a bigger role stopping corruption internationally," said Huguette Labelle, head of the Berlin-based independent pressure group.
Widespread shortcomings included the failure of about 60 percent of all the companies surveyed to disclose information about their political contributions.
Eight of the 10 worst-performing companies were Chinese, such as state-owned Chery Automobile Co Ltd, which along with Mexico's privately-owned consumer goods group Mabe scored zero points.
Wang Wei, a spokesman for Chery, said that he had never heard of Transparency International and was never contacted by the organisation.
"Chery is not publicly traded, so naturally it is not as transparent as those listed companies," Wang said, noting that the automaker does publish quarterly and annual results to its bond investors.
Transparency said Indian firms perform best in the BRICS with a result of 54 percent and several occupy the top positions in the overall index, attributing this to laws in India about how multinationals must report on subsidiaries.
Top of the class overall came India's Tata Communications Ltd which also topped the anti-corruption programmes category with 92 percent, followed by three more Tata companies.
Transparency International said public disclosure of anti-bribery measures "confirms a company's commitment to ethical conduct" and made it easier for the public to monitor them.
Emirates Airline, which is state-owned, came first in the category for organisational transparency, followed by Johnson Electric Holdings Ltd of China and Malaysian state energy company Petronas.
This category marked firms on their disclosure of data like majority and minority holdings, percentages owned by the parent company and the country of incorporation and operation - all of which is often made "deliberately opaque for the purpose of hiding the proceeds of corruption", Transparency said.
Eleven companies scored zero in this category, nine of them incorporated in China.
In the third category measuring standards of country-by-country reporting of revenues, capital expenditure, income before tax, income tax and community contributions, the Chilean retailing group Falabella scored highest with 50 percent.
Sandro Solari, Falabella's chief executive officer, said transparency was "a central element in building trust" and it would continue strengthening its ability to deliver information.
"Key financial data give citizens the possibility to understand the activities of a particular company in their country and to monitor the appropriateness of their payments to governments," said Transparency.
In a sub-index ranking just the BRICS nations, which the watchdog said account for 20 percent of global economic output and 15 percent of world trade, the companies from first-placed India were followed by South Africa, Russia, Brazil, then China.
