Renata Dwan, director of the UN Institute for Disarmament Research (UNIDIR) has stated the increased prospect of conflict is an “urgent” issue, amid growing tensions throughout the world. The senior UN security expert cites the current dispute between the US and China, who are embroiled in a trade war, as one of the main reasons for concern. Ms Dwan states countries with nuclear weapons have nuclear modernisation programmes underway and the arms control landscape is changing partly due to strategic competition.
