* Outbound M&As $118 bln in Jan-Sept, down 29 pct on year
* Nearly half of Jan-Sept deals announced in Q3
* Investors expect guidance on outbound deals at Party Congress
HONG KONG, Sept 29 (Reuters) - The value of Chinese overseas merger-and-acquisition (M&A) deals jumped in the third quarter after several large transactions, and dealmakers expect continued momentum as recovering economic fundamentals damp the need for restrictions on capital outflows.
Overseas deals this year by Asia-Pacific's most active buyers reached $118 billion at September-end, nearly half of which were announced in the past three months, Thomson Reuters data showed on Friday.
But the amount is 29 percent lower than the same period of 2016, a year in which a record $221 billion was spent on assets as varied as movie studios and soccer clubs. Such was the buying that China's government began placing restrictions on overseas deals to stop huge outflows of funds destabilizing the yuan.
The yuan has since stabilized, while China's foreign reserves have risen. The government has also been encouraging deals which support its Belt and Road initiative, whereby it aims to create a modern-day equivalent to the ancient Silk Road international trading network.
As such, investors are scouting for deals in anticipation of the government relaxing restrictions on overseas M&As, bankers and dealmakers told Reuters.
"Through the summer, on average, every week we have a new deal to look at. I've never seen this kind of activity before," said Fred Hu, chairman of private equity firm Primavera Capital.
"Now the exchange rate has stabilized. The yuan has appreciated. There's also China's longer-term geopolitical ambition - one belt, one road. If you retain capital controls, how do you obtain long-term objectives?"
Steps toward curbing overseas deal activity have varied. One such step was the banking regulator in June ordering lenders to assess their exposure to overseas acquisitions of several conglomerates.
The consequent decline in deals contributed to a 5 percent fall in the value of all Asia-Pacific M&As announced in January-September, to $754 billion, Thomson Reuters data showed.
But China's outbound M&A activity has started to rebound in recent months with many deals tied to the Belt and Road initiative, which involves countries along China's ancient trade routes and beyond, bankers said.
"If the target is in the same business, the same industry and the rationale is straightforward and the valuation is reasonable, I haven't seen (Chinese entities) not able to do a deal," said Kerwin Clayton, co-head of M&A, Asia-Pacific, at JP Morgan.
Capital controls may have thwarted multi-billion deals, but transactions of $500 million to $1 billion are still considered achievable, bankers said.
"In terms of deal size, the sweet spot this year is around $1 billion," said Samson Lo, UBS head of M&A, Asia. "State-owned enterprises as well as consortium structures can pull off bigger deals."
One such consortium sealed the region's biggest deal of the year so far in July - the $11.6 billion purchase of Singapore-based Global Logistic Properties Ltd.
Investors are now looking to China's 19th Party Congress next month for the government's policy regarding outbound investment, bankers and lawyers said.
"The 19th Party Congress may provide insight into how acquisitions are viewed and on which sectors China will continue to focus," Lo said.
