** Abu Dhabi state fund Mubadala Investment Co is in advanced talks to invest up to $1 billion in the retail division of India's Reliance Industries Ltd RELI.NS , two sources told Reuters, as investor interest in the Indian company surges. Finland's competition authority has recommended blocking Mehilainen's 362 million euros ($403 million) purchase of rival Pihlajalinna PIHLIS.HE , as the deal would reduce the number of nationwide healthcare companies to just two. Oil majors Rosneft ROSN.MM and Saudi Aramco 2222.SE are unlikely to bid in the privatization of Indian refiner Bharat Petroleum Corp BPCL.NS , sources familiar with the matter said, as low oil prices and weak fuel demand curb investment plans.

Agricultural technology firm AppHarvest said it would go public through a merger with a blank-check company in a deal that will value the company at $1 billion. Sogou Inc SOGO.N said shareholder Tencent Holdings Ltd 0700.HK would take the web search firm private in a $3.5 billion deal, making it the latest Chinese company to exit U.S. markets as tensions mount between the world's two largest economies.

French utility Engie ENGIE.PA called on Suez's management to start talks with bigger rival Veolia VIE.PA after Veolia offered last month to buy Engie's 29.9% stake in Suez SEVI.PA for 2.9 billion euros ($3.4 billion). Chinese state-owned car maker FAW Group held talks to acquire Italian truck group Iveco earlier this year but these have now been put on hold, two people close to the matter said. Japan's Nippon Telegraph and Telephone Corp (NTT) 9432.T said it will spend 4.25 trillion yen ($40 billion) to take its wireless carrier business private, in a deal that opens the path to lower prices as the government calls for cuts. Hitachi Ltd 6501.T plans to launch a sale of its materials unit as early as next month in a deal that could be worth more than 700 billion yen ($6.6 billion), three people with knowledge of the matter said.

Finnish alcoholic drinks maker and distributor Altia ALTIA.HE has agreed to buy Norwegian rival Arcus ARCUS.OL in an all-share deal, the two companies said. Australia's Jervois Mining JRV.AX said it would buy a nickel and cobalt refinery from a unit of Votorantim SA, one of Brazil's biggest diversified holding companies, as demand for metals used in batteries for electric vehicles grows.
