By Yew Lun TianBEIJING (Reuters) - Beijing Xiangshan Forum, China's biggest annual show of military diplomacy, started on Sunday although the Asian power is still missing a defence minister, who typically hosts this event. Russian Defence Minister Sergei Shoigu is listed in the forum's agenda as the first guest speaker at Monday's opening ceremony. This year's forum takes place at an awkward time for China when it is without a defence minister, whose main role is to engage with foreign militaries. On Tuesday, Beijing sacked its defence minister Li Shangfu but did not name a replacement. Chinese military leaders more senior than the defence minister have filled in for Li.
