LONDON, Nov. 16 (Xinhua) -- A British market analyst on Monday hailed the signing of the Regional Comprehensive Economic Partnership (RCEP), which launches the world's biggest free trade bloc.

Michael Hewson, the chief market analyst from CMC Markets, said on his company's website that the signing is welcome news.

"It is estimated that the rolling up of these various mini-deals into one big deal could well lessen trade friction significantly, and help offer a significant boost to Asia Gross Domestic Product (GDP) in the years ahead," said Hewson.

The RCEP agreement was signed among its 15 participating countries on Nov. 15 after more than 30 rounds of negotiation, which was launched in November 2012, as well as a number of specific leaders and ministerial meetings between the participating countries.

"The positive Asia tone generated by the news over the RCEP trade deal looks set to prevail into the start of European trade later this morning, as the new week picks up where last week left off," he said.

British stocks rose Monday, with the benchmark FTSE 100 Index up by 1.66 percent, or 104.90 points, to close at 6,421.29 points, taking their cue from a positive session in Asia.

Participating countries include the 10 member countries of the Association of Southeast Asian Nations and China, Japan, South Korea, Australia and New Zealand.

The RCEP region covers a market of 2.2 billion people, or almost 30 percent of the world's population, with a combined gross domestic product (GDP) of 26.2 trillion U.S. dollars or about 30 percent of global GDP, and accounts for nearly 28 percent of global trade.
