Beijing has often been criticized for selling arms to authoritarian regimes in Africa. DW spoke to Pieter Wezemann, senior researcher at SIPRI.

DW: What sort of weapons and in what quantities has China been selling to Africa?

Pieter Wezemann : China has primarily sold what I would call relatively low end and low technology type of equipment to a whole range of African countries. It involves armored vehicles; the numbers involved are not that high, it also involves a few tanks here and there and the cheapest simplest combat aircraft available on the market.

Which African countries have been the chief recipients of Chinese arms?

Sudan has long been a recipient of arms from China, Nigeria has bought quantities of weapons too and recently Tanzania has invested in Chinese arms. Namibia and Cameroon have bought arms in smaller numbers so it is really spread through out the continent. It's important to mention Morocco and Algeria - which have larger defense budgets than other African countries – there China has in the last five years found markets for its arms and those are probably the most important markets for Chinese arms in Africa right now.

The Chinese Foreign Ministry says it takes a cautious approach to arms exports and abides by the relevant UN resolutions and domestic laws, what does your research tell you?

Our research tells us that China exports arms to a wide variety of countries. Yes, it does abide by United Nations arms embargoes which of course are always supported by China. China has a veto against those (embargoes) so if it doesn't want them, they can say no and it won't happen. So they do abide by these embargoes but still they are quiet willing to supply to almost all countries.

What we also see is that sometimes some questions can be raised for example we saw last year that China supplied weapons to South Sudan while at the same time tried to be a peace broker in the ongoing conflict.

Another example is that there is an arms embargo to Darfur within Sudan and at times China is still willing to supply weapons to Sudan in the knowledge that Sudan will immediately transfer those weapons to Darfur which is against the United Nations Security Council resolution. So they do live up to the international laws but there are occasions where one can question their behavior in this particular regard.

In other words there are conflicts in Africa that are kept going by inexpensive Chinese weapons?

I would be a bit careful to say that. It's true that Chinese weapons do play an important role in that. But there are of course plenty of other suppliers that are willing to supply a range of countries in the region and those weapons can at times fuel conflict and military coup d'etats. It's not just China involved, there are several Western European nations, Russia, Belarus, Ukraine and others.

Putting this into perspective which countries are the major suppliers of arms to Africa and how significant are Chinese sales to the continent by comparison?

I know that China does play an important role as a total in percentage. It also plays an important role because it is willing to supply to a wide variety of countries more than other countries would do. For instance whereas China is willing to supply to Sudan and Zimbabwe, European countries would not do so. Russia is also an important supplier to a range of African states, Ukraine has supplied a lot of second hand equipment and then a number of European countries which are willing to supply to Algeria, Nigeria, and Angola and the rest.
