* KOSPI index falls, foreigners buy * Korean won inches down against U.S. dollar * South Korea bond yields up SEOUL, Nov 30 (Reuters) - Round-up of South Korean financial markets: ** South Korea's KOSPI stock index weakened on Friday due to concerns over a slowdown in China, as investors awaited the outcome of the U.S.-China leaders' meet at the G20 summit on Sunday. The Korean won fell, while bond yields rose after the country's central bank lifted rates, amid analyst expectations that the rate would be on hold throughout next year. ** Growth in China's vast manufacturing sector stalled for the first time in over two years in November as new orders shrank, adding pressure on Beijing ahead of high-stakes trade talks between presidents Xi Jinping and Donald Trump this weekend. The official Purchasing Managers' Index (PMI), released on Friday, fell to 50 in November, missing market expectations and down from 50.2 in October. ** South Korea's central bank raised its policy interest rate on Friday for the first time in a year in a widely expected move aimed mainly at containing a boom in parts of the country's property market.

The first stage was cancelled in May last year, it said. ** Samsung Electronics' supplier Toptec Co Ltd plunged as much as 13.7 percent on indictment over information leak.
