Foreign direct investment into China stabilized in the first half of 2017, and the nation's outbound direct investment took a nosedive as authorities curbed irrational deals and fine-tuned the investment portfolio, Ministry of Commerce officials said on Thursday.

FDI in China rose by 2.3 percent year-on-year in June to 100.45 billion yuan ($14.82 billion). During the first six months, the inflow stood at 441.54 billion yuan, down by 0.1 percent, the Ministry of Commerce said on Thursday.
