China-led AIIB development bank holds signing ceremony

China has hosted the signing ceremony of the Asian Infrastructure Investment Bank (AIIB), a new international financial institution set to rival the World Bank and Asian Development Bank.

Delegates from 50 countries signed articles that determine each member's share and the bank's initial capital.
The UK, Germany, Australia and South Korea are among the founding members.
Japan and the US, which oppose the AIIB, are the most prominent countries not to join.
The US has questioned the governance standards at the new institution, which it sees as spreading Chinese "soft power", and tried to persuade others to stay away.
The AIIB, which was created in October by 21 countries, led by China, will fund Asian energy, transport and infrastructure projects.

This is not just a diplomatic win for China, it serves an important economic objective too. China wants to move away from building infrastructure at home. Its engineering giants need somewhere else to build ports, roads and cities.
Answer - lend the region the money to pay Chinese companies to build a 21st Century Asia according to a Beijing master plan and with Chinese influence at its core.
This is China under President Xi Jinping flexing its muscle as a major power, but many observers say the move might not have come so soon if the US had been able to lead the reform of existing global financial institutions to make room for China at the top.
After 30 years of breakneck Chinese growth, the distribution of power in those institutions no longer reflects the reality of the global economic landscape.
One British official told me: "If an alien landed on earth they would be puzzled by its international financial institutions as China is grossly underrepresented."

Country delegates gathered at Beijing's Great Hall of the People for the signing ceremony.
Australia was the first country to sign the articles of association creating the AIIB's legal framework, followed by 49 other members. Seven more countries are due to sign by the end of the year.
Most Asian countries and countries from the Middle East and Latin America have joined, with the launch of the Beijing-led bank being hailed as a diplomatic and strategic success for China.
It is one of several institutions China has created to push its own economic agenda, largely driven by frustration over its lack of influence in the big global financial institutions such as the World Bank, says the BBC's Martin Patience in Beijing.
The AIIB will begin with authorised capital of $50bn (£31.8bn), eventually to be raised to $100bn.
China will hold a 30.34% stake making it the largest shareholder of the bank, Reuters quotes China's Finance Ministry as saying.
This would give China 26.06% of the voting rights within the multilateral institution.
India will be the second-biggest shareholder with a possible 10-15% stake, while Russia and Germany will make up the third and fourth biggest member stakes, Reuters news agency reports.
Chinese Finance Minister Lou Jiwei said on Monday he was confident the AIIB could start functioning before the end of the year, according to Reuters.
