SHANGHAI, June 14 (Reuters) - Mainland China stocks inched up on Friday as gains in brokers outpaced weak sentiment caused by the falling yuan, ahead of key domestic economic data.

Hong Kong stocks declined on Friday and posted a weekly loss of 2.3%, while China's blue-chips recorded their fourth straight week of losses.

Market participants braced for Chinese credit lending data for May, due later in the day, and the central bank's rollover of maturing medium-term policy loans next Monday for more clues on the performance of the broader economy. The country will also release May activity data on Monday.

China's yuan eased to a fresh seven-month low against a firmer U.S. dollar on Friday as the Japanese yen fell after the Bank of Japan (BOJ) stood pat on rates and said it would trim bond purchases in the future.

Separately, the United States said it was considering taking additional steps against Chinese companies that have been supplying Russia's defense industrial sector, hurting sentiment.
