求翻译：　　国际知名经济学家加特曼近日也表示，中国整体储备中黄金所占的比例“令人震惊的低”，但这种情况最终将得以改善。加特曼表示，中国将成为一个低调的、但持续的黄金买家，同时也是其他资产的卖家。除此之外别无选择。但预计这一过程进行得很慢，约为几年或几十年，而非几个星期或几个月。是什么意思？

　　Internationally renowned economist Dennis Gartman said in recent days, the proportion of gold in China's overall reserves "shocking low", but that will eventually be improved. Dennis Gartman says China will be a low-key but continuing gold buyers, but also other asset sellers. Otherwise have no choice. But it is expected to slow this process, some for years or decades, not weeks or months.
