GLOBAL ECONOMY-Momentum and risk: world economy enters 2017 with winds fore and aft

Factories across the world fired up -- or at least kept up activity in January -- with some registering multi-year output, just as a barrage of political risks threaten the global economy with potential harm.

Rising protectionism from the United States, concerns over how Britain's negotiations on leaving the European Union will pan out, and national elections across Europe's largest economies all lie ahead for the global economy.

But entering 2017, economic growth gathered momentum, according to surveys released on Wednesday, following on from last year thanks to a bounce in consumption.

Euro zone factories registered the fastest activity rate for nearly six years, China's activity expanded for the sixth month and Japanese manufacturing growth was the fastest in almost three years.

Even in Britain, where a slump in sterling since the June referendum stoked the sharpest rise in factory costs on record last month, growth remained robust.

"So far momentum is pretty strong heading into 2017," said Jacqui Douglas at TD Securities. "But political risks are definitely one of the biggest this year and given the surprises we had through 2016 it's really hard to tell what's in store."

Among unexpected events last year was Britain's vote to leave the EU and the election of U.S. President Donald Trump, both seen as the result of anti-establishment anger among voters who feel left out of the wealth of nations.

IHS Markit's final manufacturing Purchasing Managers' Index for the euro zone rose to 55.2 in January from December's 54.9, its highest since April 2011. A Markit/CIPS UK factory PMI edged down to 55.9 from December's 2-1/2 year peak of 56.1, matching the consensus forecast in a Reuters poll.

Anything above 50 indicates growth.

A similar survey for the United States is due later on Wednesday, expected to show factories in the world's largest economy also increased activity.

TOKYO TEMPERING TRUMP

A stronger U.S. dollar helped major economies such as Japan, where export orders surged, Markit/Nikkei PMI numbers showed, a welcome sign for the economy along with recent data suggesting a more durable recovery may be underway.

However, those encouraging signals sit uncomfortably with the growing threat from Trump's trade policies. Japan is moving to temper the risks with plans to show Trump its firms are ready to create U.S. jobs, according to a document whose contents were revealed to Reuters.

In export-reliant Asia, and other regions where global supply chains are closely inter-linked, Trump's election is a particular risk to both world trade and broad economic growth if the new president follows though on his "America First" policies.

"The uncertainty surrounding future market access to the U.S. is bound to weigh on investment activity as companies await regulatory certainty," said Frederic Neumann, co-head of Asian economic research at HSBC in Hong Kong.

"I suspect there's going to be a lot of capital expenditure expansion projects that will be put on hold as long as the uncertainty surrounding the trade environment persists."

In China, the world's second-biggest economy, growth was led by an investment and construction boom that has helped spur global growth. Its official PMI stood at 51.3 in January, slowing marginally from 51.4 in December.

Analysts question whether Chinese growth will be sustainable once the impact of earlier stimulus begins to wear off and if the property market cools. They warn a slowdown in the Asian economic powerhouse could ripple across the region and beyond.

"Within China, we expect that real estate will slow down, because the government is quite keen to contain housing prices," said Louis Kuijs, head of Asia economics at Oxford Economics in Hong Kong.

Other regional economies like Indonesia showed positive momentum in manufacturing activity, while Indian factory activity returned to modest growth in January, bouncing from a contraction in December triggered by the government's scrapping of high value banknotes.

Even in laggard South Korea where manufacturing contracted for the sixth straight month, exports rose at the fastest pace in nearly five years.

"We remain quite cautious how much of an acceleration in growth we can see in this pretty challenging climate," Oxford Economics' Kuijs said.

"Things like PMI are timely indicators of the hard data but sometimes they do run ahead, and the improvement in actual data doesn't materialise."
