Commodities in China rallied in Wednesday's trade with steel and iron ore rising over 5 percent. Coke and silver climbed 4 and 3 percent respectively. Other commodities such as coal, bean pulp and copper all posted increases of over 1 percent. 

Commodities including iron ore and coal have recently experienced a rally that has drawn market attention. The trend was broken a bit last week when most commodities retreated on Thursday and Friday. 

Analysts say investors have become more cautious since the first quarter GDP was published. However, a warm up of the real estate market as indicated by this week's new housing figures has given commodities a boost of confidence.
