* Copper prices fall for third straight session

* China vows to strive for economic growth in Q2

May 26 (Reuters) - Copper extended losses to a third session on Thursday as concerns grew that the global economy might plunge into a recession and dampen demand for industrial metals.

Three-month copper on the London Metal Exchange was down 0.5% at $9,328.50 a tonne, as of 0536 GMT. The most-traded July contract on the Shanghai Futures Exchange fell 0.2% to 71,300 yuan ($10,581.78) a tonne.

Copper is often used as a gauge of global economic health. Prices of most other base metals also fell on both the Shanghai and London exchanges.

The gloomy economic outlook for top metals consumer China as it struggles to contain COVID-19 outbreaks, and ongoing policy tightening by global central banks kept markets on edge.

"The lockdowns in China are part of the growing narrative around the risk of a global recession," said Rodrigo Catril, a National Australia Bank market strategist.

CHINA: China's central bank said on Thursday it would promote more credit for smaller firms and boost financial institutions' confidence to lend funds, as policymakers struggle to get the COVID-stricken economy back on track.
