China's economy could suffer if the euro weakens meaningfully in coming months, broker UOBKayHian said Wednesday. "A stronger yuan will surely dampen demand for Chinese goods," said UOB analysts said. The euro zone is China's largest trading partner, accounting for 15.1% of its external trade, and UOB said machinery exports, which make up about 50% of total Chinese shipments to the region, would be most at risk. "Weak demand in this segment could bring more headwinds for China's manufacturing sector growth, which in turn will affect the country's economic growth," UOB said. The euro (CUR_EURUSD) traded slightly higher Wednesday, rising to $1.3196 , up from $1.3187 late Tuesday.
