The fact that violence is still simmering in eastern Congo -- and despite the costs that extraction imposes on the Congolese people -- has not been enough to deter Beijing from wooing Congo's government for access to the country's abundant resources. So, if there's any thought that war in Afghanistan might dissuade Chinese investment there, it's best to dispense with that notion immediately.

China, which has a narrow land border with Afghanistan, already invests heavily in the war-torn Central Asian state. The state-owned China Metallurgical Group has a $3.5 billion copper mining venture in Logar province. Chinese companies ZTE and Huawei are building digital telephone switches, providing roughly 200,000 subscriber lines in Afghanistan. Even back in the war's early days in 2002 and 2003, when I worked in Afghanistan, the Chinese presence was acutely visible in Kabul, with Chinese laborers on many building sites and Chinese-run restaurants and guesthouses popping up all over the city. As Robert Kaplan has pointed out, these investments come with a gratuitous hidden subsidy from the United States -- which has defrayed the enormous costs of providing security amid war and looting.

With its massive wealth, appetite for risk, and willingness to underbid others on labor costs and human rights conditionality, China is the odds-on favorite for development of any new Afghan mineral resources. Chinese firms will control the flow of new funds, and the way those funds are distributed between the central and local governments. It's all well and good that Barack Obama's administration has recommitted to building civil projects in rural Afghanistan, but consider the relative scale of building a school to establishing a multimillion-dollar mine (not to mention the transport networks and infrastructure required to get the extracted minerals out) and it's easy to see what kind of influence the Chinese will bring to the table.

Although many have warned of a new Sino-colonialism, Brautigam's work suggests that perhaps China's awareness of its gargantuan and growing need for foreign export markets will make it a better "colonial" power than any European country ever was.

Stability in Pakistan should be an important goal for China. It is by now clear that the Taliban's campaign west of the Durand Line is inextricable from the destabilizing efforts of Islamist militants in Pakistan. If China does not want another nuclear basket case on its border, then it should care deeply about instability in Afghanistan. Currently, however, Beijing is still freeloading, relying on Washington to provide security for its limited interests. Perhaps the tantalizing prospect of $1 trillion in minerals might be enough to change the strategic equation.

Uzbeks are the largest ethnic minority in Kyrgyzstan after Russians, making up over 13 percent of the population. In Osh and Jalalabad, however, Uzbeks constitute the majority of the population. The Uzbek minority is largely excluded from Kyrgyzstan's political system, though they dominate the country's merchant class. Disputes over water and land use between the Uzbeks and Kyrgyz are common in the south.

in 1990, when the Soviet military was unable to put a stop to a three-month-long inter-ethnic battle between Uzbeks and Kyrgyz in Osh that resulted in hundreds of deaths, it was taken as a sign of Moscow's diminished power over its regions.

But the early years of Kyrgyz independence, the two groups were generally able to settle disputes without resorting to violence, much of which was due to former leader Askar Akayev's policies of rapprochement. He made the advancement of ethnic minorities a priority, granting land to the Uzbek community and building Uzbek language universities under a policy known as "Kyrgyzstan - Our Common Home." Uzbeks were overwhelmingly supportive of Akayev, but their fortunes turned for the worse when Bakiyev overthrew him in 2005. While he never directly suppressed the Uzbek community, Bakiyev mostly ignored their grievances and allowed the ethnic situation to return to its normal state of animosity. Under his leadership, drug traffickers and organized criminal groups found a safe haven in Kyrgyzstan's south, further frustrating local residents. All the same, the president's firm hand kept ethnic violence to a minimum.

Since Bakiyev's downfall earlier this year, however, ethnic tensions in Kyrgyzstan have spiralled out of control. In April, a group of Meshketian Turks, a small Muslim minority group, were attacked by provocateurs in the outskirts of Bishkek. In May, ethnic Kyrgyz and Uzbeks clashed in much small riots in Jalalabad in a preview of this weekend's violence.

The heavy deployment of troops to Osh has left other parts of the country vulnerable and fears are running high that the unrest could spread to other areas.

the Kyrgyz military, predominantly made up of ethnic Kyrgyz, may itself be part of the problem. Many of its leaders share the suspicion that Uzbekistan plans to invade Kyrgyzstan to protect water resources and expand its territory. They are thus inclined to look upon local Uzbek residents as a fifth column; for their part, many Uzbek residents fear that they will be specifically targeted and are disinclined to trust the military to fairly resolve the dispute.

t is still the only state in Central Asia with viable and active political opposition, professional NGOs, and independent journalists. The upcoming referendum and the parliamentary elections that would follow could set a powerful example for the region. However, if Kyrgyzstan is left alone in solving its deep-rooted ethnic strife, the escalating violence threatens the very future of democracy in Central Asia.

Merkel and Sarkozy said they were sending a joint letter to Canadian Prime Minister Stephen Harper, the G20 chairman, seeking to accelerate reforms in financial regulation.The letter also pushes for a global tax on financial transactions and agreement in principle on a levy on banks to pay for the cost of financial crises, Merkel said.
