BEIJING, Aug 2 (Reuters) - Shanghai copper fell more than 1 percent in early trade on Thursday, after U.S. officials confirmed that President Donald Trump's administration proposed an increase in tariff rate on $200 billion worth of Chinese goods. Fears that the trade row between the world's top two economies could hit demand for industrial metals saw Shanghai copper shed 3.4 percent in July, while London copper posted its biggest monthly fall since December 2016. FUNDAMENTALS * SHFE COPPER: The most-traded September copper contract on the Shanghai Futures Exchange fell 1.4 percent to 49,240 yuan ($7,230.44) a tonne as of 0155 GMT, having earlier slipped to 49,010 yuan, its lowest since July 24. * LME COPPER: Three-month copper on the London Metal Exchange slipped 0.2 percent to $6,162.50 a tonne, after closing down 2 percent in the previous session. * TARIFFS: U.S. President Donald Trump sought to ratchet up pressure on China for trade concessions by proposing a higher 25 percent tariff on $200 billion worth of Chinese imports, his administration said on Wednesday. * FED: The U.S. Federal Reserve kept interest rates unchanged on Wednesday but characterized the economy as strong, keeping the central bank on track to increase borrowing costs in September. * SHFE NICKEL: Shanghai nickel was down 2.7 percent at 110,360 yuan a tonne, after a 3.1 percent drop in LME prices on Wednesday. The ShFE will raise the transaction fee for November nickel futures to 6 yuan per lot from 1 yuan, effective Aug. 3. * LME NICKEL: The LME launched on Wednesday a consultation to trial in the first quarter of next year the use of its electronic system to determine closing prices of the three-month nickel contract instead of open outcry. * RIO: Global miner Rio Tinto, said on Wednesday its first-half profit grew 12 percent, missing estimates and sending its shares lower even though it earmarked an additional $1 billion to buy back London-listed stock.
