Dec 28 (Reuters) - London's internationally focussed FTSE 100 gained on Wednesday as China's dismantling of COVID-19 restrictions pushed miners and banks higher, while the index still remained cautious of surging COVID cases.

China scrapped its quarantine rules for inbound travellers starting from Jan. 8 on Monday, but global markets turned jittery as COVID cases rose in the world's second-largest economy.
"If the cases don't rise to the point that paralyses economic activity, then it is not going to be a big problem for market sentiment," said Ipek Ozkardeskaya, senior market analyst at Swissquote bank.
Miners gained 0.5%, tracking rising copper prices after top-consumer China's easing boosted hopes of improving demand.
China-focused insurers and banks such as Prudential and HSBC Holdings also rose, gaining 0.6% and 1.5% respectively.
The 200-day and 50-day moving average indicators for the FTSE 100 intersected for the first time since July, a technical phenomenon referred to as the "golden cross".
The "golden cross" indicates a positive trend that is strengthening because of the rising commodity and energy prices, and the trend could continue in the first half of 2023, Ozkardeskaya added.
The blue-chip index is up 1.5% year-to-date, handily outperforming the broader STOXX Europe 600 index, which is expecting falls of over 12%.
