* China's Premier Li says Q2 growth to be higher than Q1

* PZ Cussons slips after profit warning

* JD Sports Fashion down after flagging weakness in North America

* FTSE 100 up 0.1%, FTSE 250 adds 0.5%

June 27 (Reuters) -

British equities rose on Tuesday as China-exposed stocks jumped after Beijing said domestic growth would be higher in the second quarter, while mining stocks rose on higher metal prices.

The blue-chip FTSE 100 rose 0.1%, while the more domestically-focussed FTSE 250 midcap index added 0.5%.

China's Premier Li Qiang told delegates at the World Economic Forum in Tianjin that the country's economic growth in the second quarter will be higher than the first and is expected to reach the annual economic growth target of around 5%.

Li also said that Beijing would roll out more effective measures to expand domestic demand and open markets.

"Investors want to see those growth figures actually being achieved rather than just promises that they will be achieved," said Danni Hewson, head of financial analysis at AJ Bell. "There has been disappointment (in the past), but don't bet against China when the authorities really get their finger out."

China-exposed banks HSBC and Standard Chartered added 0.4% and 1.2%, respectively, while insurer Prudential gained 1.7%.

Industrial metal miners added 0.4% as copper prices edged higher, while precious metal miners rose 1.1% tracking higher gold prices.

The exporter-heavy FTSE 100 is on track to post quarterly losses after two straight quarters of gains, as surging domestic inflation and continued interest rate hikes by the Bank of England dented risk appetite.

BoE Monetary Policy Committee (MPC) members Swati Dhingra and Silvana Tenreyro would be speaking on engagements later in the day.

Among individual stocks, JD Sports Fashion slipped 4.8% after the sportswear retailer said there had been some softening in trade in its North American business in June.

BT Group fell 3.5% after UBS downgraded the telecoms firm to "sell" from a "neutral" rating.

Petrofac Ltd slipped 3.5% after the oilfield services firm forecasted lower first-half revenue in its largest unit.

PZ Cussons slumped 3.9% after the soap maker said that devaluation of the Nigerian currency naira would adversely impact its profit next year.

Elsewhere, a survey by the British Retail Consortium showed that British shop price inflation slowed this month. (Reporting by Shashwat Chauhan in Bengaluru; Editing by Sonia Cheema and Eileen Soreng)
