Fortune unveiled its annual Fortune Global 500 list of the world's largest companies, ranked by revenue, on Wednesday. The magazine found that both sales and profits fell 11.5% last year. While Walmart (WMT) - Get Report still holds the No. 1 spot, the next three largest companies, according to Fortune's analysis, are Chinese state-owned energy giants: State Grid, China National Petroleum and Sinopec (SNP) - Get Report .

Although more than 100 Chinese companies made the list, the number of American companies increased to 134 from 128. China's second-largest retailer, JD.com (JD) - Get Report , made its first appearance on the list in the 366th slot. Competitor Alibaba (BABA) - Get Report did not make the cut as its revenue was insufficiently large, while its gross merchandise volume is much higher than JD's.

Hurt by low oil prices, energy companies, except for their Chinese peers, took a beating. Companies moving down on the list include Royal Dutch Shell (RDS.A) , ExxonMobil (XOM) - Get Report , Britain's BP (BP) - Get Report , France's Total (TOT) - Get Report , Chevron (CVX) - Get Report , Schlumberger (SLB) - Get Report , Halliburton (HAL) - Get Report and ConocoPhillips (COP) - Get Report .
