The documents released by the transparency group are allegedly associated with TiSA (Trade in Services Agreement) negotiations, which have been taking place in secret since early 2013. The participants of the talks include 24 WTO members, such as the US, EU and other countries including Turkey, Mexico, Australia, Pakistan and Israel.

According to WikiLeaks, the economies of the member countries now comprise two-thirds of global GDP. Their services "now account for nearly 80 percent of the US and EU economies," the group says, adding that "even in developing countries like Pakistan [they] account for 53 percent of the economy."

The European Commission web source says the participants in the agreement, which is set "to liberalize trade in services," "account for 70 percent of world trade in services." The "talks are based on proposals made by the participants," the EU source adds, saying that "TiSA aims at opening up markets and improving rules" in a number of areas, including financial services, transport and e-commerce.

A number of the world's economies, including all the BRICS countries – Brazil, Russia, India, China, and South Africa – are excluded from the TiSA negotiations, which purport to benefit the global economy.
