As the global economic, financial and political balance of power shifts from the West to the East, it is becoming increasingly evident that we are living through the tail end of half a millennium of Western supremacy. Consequently, Zimbabwe must be commended for presciently adopting a "Look East policy" over a decade ago.

However, the nation must now also look to strengthen ties with the fastest developing nation not found in the East, namely Brazil.

The Look East policy has been beneficial but in many ways, Brazil outclasses the other BRICs in the East. Unlike China, it is a democracy.

Unlike Russia, it exports a great deal more than arms and oil. Unlike India, it has no insurgents, no hostile neighbours or internal ethnic or religious conflict.

From an economic speck at the outset of the 19th century, the US by 1914 had grown into the world's largest economy and leading exporter.

This dominance continued and grew for almost a century and a few years ago, the US, with only five percent of the world's population, accounted for approximately a quarter of the world's economic output.

The US was responsible for nearly half of global military expenditure and crucially had the most extensive cultural and educational soft power.

However, as it stands, the American empire is falling rapidly.

Much like the Roman empire, America's Empire is decaying from within rather than from despicable terrorists or barbarians at the gates.

The three interconnected forces that destroy empires -- lack of money, military over-reach and the catastrophic loss of self-confidence that stems from the other two -- have coalesced with astonishing speed since the Twin Towers tragically fell.

How did we get here, when all's been well but did not end well?

When George Walker Bush was elected President by five of the nine Supreme Court judges, he inherited a nation swimming in money and basking in its post-Cold War hegemony.

A mere two Presidential terms later, despite the residual economic boom and surplus President Clinton left him, he doubled the budget deficit by spending trillions on discredited wars and billions more on tax breaks for the rich.

He inherited a swaggering empire at the zenith of its military, financial and indeed cultural might, and bequeathed to President Obama a rattled country in precipitous decline.

As a result, President Obama's cards were marked in advance and he now speaks with diminishing authority at high stakes international tables.

He sounds increasingly like the eloquent voice of an empire in decline.

Obama's wise refusal to dominate a questionable NATO campaign and the President's choice to "lead from behind" confirms something unthinkable only a decade ago.

The President of the United States of America is no longer the leader of the free world, but a fellow-traveller in a free world without a leader at all. Watching America's unipolar moment end is rather like watching a drunken giant begin to loose its footing. A sobering reckoning of some sort seems inevitable; and it is difficult to see how the US can regain its footing.

Five hundred years ago, what had given the West the edge over the Rest were five key features: the capitalist enterprise, the scientific method, global imperialism, the "Protestant" ethic of work and finally, the consumer society and capital accumulation as ends in themselves. Brazil has clearly replicated the first and the second and may be in the process of adopting others with some alterations (consumption and the work ethic).

Only the third -- imperialism -- shows little sign of emerging in Brazil towards Africa.

In-fact, quite the contrary, Brazil does a great deal of good in Africa: Brazil's relations with Africa date from the beginning of 17th century, when many merchants and entrepreneurs of West African origin returned to the continent and established regular shipping lines and commerce flourished from Bahia. Prior to 1980 Brazil was instrumental in pushing for Zimbabwean Independence at the UN and helped establish the African Development Bank.

More recently, whilst in office from 2003 to 2010, former President Lula da Silva presided over an era of unprecedented political and economic engagement between Brazil and Africa.

In that time Brazil has doubled its number of embassies on the continent to 34, tripled its exports to over US$9.5bn in 2010 and quadrupled trade with Africa.

Unlike the West's well known multinational corporational and imperialist approach to Africa and unlike China's economic and resource extractive model, Brazil emphasises "South-South" co-operation in which social, political and cultural concerns are as important as economic concerns.

As much as 50 percent of Brazil's population traces its heritage to Africa, and some parts of the country bear closer resemblance to sub-Saharan Africa than mainland Latin America.

Brazil is the second-largest black country in the world after Nigeria, with 76 million Afro-Brazilians out of a total population of 190 million.

"Brazil would not be what it is today without the participation of millions of Africans who helped build our country. Whoever comes after me has the moral, political and ethical obligation to do much more," said President da Silva in his last address on the continent.

Zimbabwe must now engage the new administration and recognise and expand mutually beneficial areas of political, economic and social cooperation between the two nations.
