June 11 (Reuters) - Major stock markets in the Gulf ended lower on Sunday in response to falling oil prices and weaker-than-expected Chinese economic data. The Qatari Stock index (.QSI) dropped 0.5%, extending its losses to a second session. The index recorded a drop in all sectors with Gulf's biggest lender Qatar National Bank (QNBK.QA) falling 0.6% and Qatar International Islamic Bank (QIIB.QA) shedding 0.7%. However, the oil giant Saudi Aramco (2222.SE) and the kingdom's biggest bank Saudi National Bank (1180.SE) lost 0.3% and 0.9% respectively. Outside the Gulf, Egypt's blue-chip index (.EGX30) climbed 1.3%, extending its previous session gains.
